Coulomb Excitation of Odd A-Nuclei by Heavy Ions 76965
SOV/56-37-6-5/55
In previous investigations, in which chromium was
irradiated with protons or CL-particles, are not
due to coulomb excitation of the corresponding levels
in chromium. It was shown that lines associaW with
nuclear levels owing to the CL-excitation (Rb ,
Snll7, Sn'19) are actually
coulomb excitation. The partial

TEXT: The present paper was read at the 10th All-Union Conference on
Nuclear Spectroscopy, which was held in Moscow from January 10 to
January 27, 1960. The experiments described in the present paper were
carried out with 16.3-Mev and 36..O-Mev nitrogen ions and 25.2-Mev neon
ions. Results are given in Table 1, Chromic oxide targets were used, which
contain the isotopes Cr52 and Cr54, as well as natural, vaporized chromium.

TITLE: Coulomb excitation of the nuclear levels of P31, S33, Mn55,
and Pr141 by means of Ne 20 ions
PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, v. 25,

TEXT: The measurements were made by means of a scintillation spectrometer
with a NaI-T1 crystal (40 mm in diameter, 40 mm in height) and by means of
a photomultiplier of the type +)'y-11 (FEU-11). The electronics
consisted of a pre-amplifier, a cathode follower, an overchargeable
amplifier and an AHA-2 (AMA-2) 63-channel pulse height analyzer
connected in parallel and an AW 100-1 (AI 100-1) 100-channel pulse height
analyzer. Method of measurementp apparatus I and course of the

described in three previous papers (Refs. 1-3). In the case of nitrogen
ions the errore are below 159;, but they may attain from 20 to 25j"O' for
neon ions. The following was observed when measuring the energy of beam
particles by means of deflection in a magnetic field: After deflection,
the beam is split into several components corresponding to different
charges of tho accelerated ions. The change of the iona falling into
the beam catcher causes the change of the ratio current strength / number
of beam particles in the beam, which means that it influences the accuracy
of calculation of the Coulomb excitation cross section. In the
experiments concernedg the bombarding particles were quadruple-charged
NeZO ions with energies of 23.2 and 27.8 Mev. The amperage of the ion
beam measured on the target was %,,1#10-8a. Th7 measurement results are
given in the attached Table. R0 - 1.2-10-13A1 3 cm was set. Figs. 1,2,
3,4 show the instrumental y-spectra taken with Ne20 ions. The following
notes are added concerning the individual elements: p3l: The Coulomb
excitation of the level with AE - 1.26 Mev of P31 was examined with the
aid of ions N020 with an energy of 27.8 Mev. The target was pressed from
a red phosphorus powder. The spectrum contains a gamma line with
