However, the data-jbtained by different authors concerning the individual calcium hydrosilicates do not always agree with each other. In order to obtain a clear picture of the phase composition of complicated systems of hydrosilicates a comprehensive phase analysis must be employed. In this connection the knowledge of such constants of hydrosilicates as the interplanar epttcing~ the line intensity in X-ray diagrams, the temperature and the jard 1/4 magnitude of thermal effects, the position of the! absorption SOV/20-120-4-45/67 Inventigation of the Properties of Calcium Hydrosilicates bonds in the-infrared spectra and similar data .':a necessary. Apart from these data an understanding of tile technical properties of-the individual hydrosilicates must be reached if thp development of production methods of materials with prescribed properties is intended. In the Institute "Asbest- tsement" a number of the most important hydrosilicates was synthetized, and their properties were studied. The X-ray diagrams (Fig 1) were recorded by means of CuKa radiation -ith a nickel filter on a diffractometer of the type UPC-50I vith a Geiger counter. The curves of thermal differential analysis and of weight losses oi, heating (Fig 2) were de- termined on a thermalbalance. The absornti-on 9 eotra in the p infrared range (Pig 3) were taken*on a INS-11 spectrometer, Electron microscope images were obtained with a microscope EM-3 with an electron-optioal scale factor of 3900.

Low-bnsicity*hydrosilicates CS11(B) with a fiber-like texture of a basicity of from 1,25-0,8 play an important nart in the autoclave hardening of sandy oemente and low-basicity lime-sand mixtures. Together with tobermorite they are the cause for the high strength of these ninevals. They were produced by a hydrothermal 0treatment of v mixture of CO- and silicagel (1:1) at 175 9 for 1, 2 and 3 hours or for from 6 - 6 hours.

The author first investigates the spin-Hamiltonian of the interaction between a localized electron and the magnetic moment of the lattice nucleus as well as a simplification of th4a Hamiltonian. The t,hird part of the paper deals with U - centers. There i proof of the fact exists, by the way, indirect experimenta Card 1/3 that the absorPtion-U 2- band in KOI is due to the prosence of The Spectrum of the Frequencies of Double Spin SOV/56-36-1-17/62 Resonance in the.Centers of the Coloration of Alkali-Halogen Crystals hydrogen.atoms in the space between the lattice nodos. The. author determines the frequencies of double spin retionanoe which occur in the interaction '-twoen the electrcn~of a U2- center and the 8 xioighbort:I.,b nuclei. The hydrogen. atom is, in this connection, assumed to be in the center of the cube. The F+- center, which is discussed in the following 2 chapter, forms a eyatem consisting of 2 negative vacancies and an electron, which are located in an ion crystal.. Formulas are written down for the frequencies of spirt-nucleus transitions, which are due to the interaction of the spin of the localized electron and the magnetio moment of tha k-th nucleust these formulas relate to centers in the plane (100) in the 2 s symmetric case. Next, the respentiva results obtained by g.;culating the freque-neies for the asymmetric model of a -er of this paper T~ (~,!nter axe investigated. The last chap. discusses the M- oenter.s.

Even in the symmetric case considerable differences are to be expected between the frequencies of the ions of a given group, because the ions in such a group have different positions with respect to the M-center.

In the present paper, the authors cionsider the ::pin- lattice relaxation as being caused by a change in the energy of the con- tact interaction between the spin of a localized electron and a nucleus, which is caused by thermal lattice.vibrations. This relaxation mechanism has always a relaxation time i (Ref, J) which correspondn to a proi-eas Card 1/3 84422 Spin-Lattice Relaxation of Local Electron S/056/60/039/004/040,1()40 Centers in Nonmetallic Crystals B006/BO56 in which a re-orientation of the nuclear spin occurs simultaneously, which compensates the change in angular momentum. There also exists another relaxation mechanism which is due to the re-orientation of the electron spin without corresponding re-orientation of the spin of those nuclei which cause the hyperfine structure of the paramagnetic absorption lines of local electron centers (relaxation time Ts)~ This division of relaxation mechanisms is reasonable also from the experimental viewpoint (for non- metals). The theory is developed in all detail for crystals in which the wave function of the localized electron can be chosen in atomic orbit approximation. The relations obtained may be considerably simplified by studying an F-center; for a M-type crystal, a practical example it) calculated; and for an P-center of such a crystal, the maxi ,mum and minimum relaxation times are numerically determined (corresponding to the maxim= and minimum sound velocities).

(USSR) ABSTRACT: Studies of paramagnetic resonance in F-centres of alkali-halide salts and in donor impurities in .silicon show that at sufficiently low temperatures broadening of paramagnetic resonance lines is essentially due to the interaction of a localized electron with magnetic moment* of nuclei of the crystal (Refs-1-3). It was therefore of interest to find the spin-Hamiltonian for such an interaction.

PERIODICALS Doklady Akademii Luk SSSR, Vol 113, Nr 2v PP 450 - 453j 1957 (U.S.S.R.) ABSTRACTS Cirripeds are the most common components of overgrowthe on sea-going vessels. On the ship bottom they are often carried into regions far away from their original domain, where, under favourable conditions, they can propagate and colonize new regions. Thus Balanus eburneU8 came from North America into the Black Sea, many other organisms from the southern hemisphere into the northern one etc. The Caspian Sea turned out to be especially favourable for the naturalization of several intervertebrates and a few fishes from the Black Sea. Thus, the B.improvieus (1955) came, here from the Black Sea through the Volga-Don-Canal. In '1956 also Balanus eburneus was found here (on stakes and buoys in 'the Kraanovodek-bay and on wooden stakes of the Orguohinakiy.-island, Card 1/3 here in connection with Balanus improvisus). Balanas imp:,-ovisus Cirripeds. PA - 3374 is obviously distributed all over the sea. kn exception is the Baku-bay where the water contaminated by mineral oil obviously is ,pian specimens not suited for ciftipeds. When comparing the Cas of-both kinds with those from the Black Sea some differences be6ame evident: Balanus improvisus shows solid, thickwalled shells and is considerably larger, which apart from its vast distribution gives evidence of favourable conditions prevailing here. Balanus eburneus colonizes in the Kraonovodak-bay on shells of the mollusk Mytilaster lineatus (also imported) and is smaller than specimen from the Black Sea. It might during the short period not have been able yet to attain its maximum size. In the Caspian as well as in the Asov Sea Falanue improvisus competes with Mytilaster lineatus in finding room to settle on vacant sur- faces. Balanus improvieus is frequently found on ships, whereas Balanus eburneus occurs more rarely. The cirriped overgrowths do not only retard the speed of ships but also intensify the corrosion of the hull. They cur. through the paint with the sharp edges of their shells and give seawater access to the metal. Whbn growing they shove away the layer of paint and thus penetrate under the paint. The phenomenon of these crustaceans in the Caspian Sea makes it necessary to apply an anti-overgrowth paint with an admixture of DDT if necessary, as a coating for Card 2/3 ships and buoys.
