However, these processes require a change of the conception about the
ionization sourcl-? in the upper atmosphere. According to these results
the neutralization of the particles takes part in the ),onosphore, mainly
by trunsfer r,--' the atomic ions into moleou lar ions and subsequent
neutralization of the molecular ions. K. I. Gringauz and several
western researchers have investigated the electron concentration above
an altitude of 80 km, and the data are given in Table 1. The following
differential equation for the vanishing of electrons is based on these
data: dn /dt - an n a-'n+n2/(n+ + n2 . Thereforep thero are

recombination processes of higher intensity at these altitudos au has
been assumed in the past. From this it follows also that much utrongor
ionizing rays (10-100 erg/om2 see) are found to exist than has been
assumed in the past, in order to conserve the high degree of ionization.
The newest data about the short wave spectrum of solar radiation have
been studied in this connection. In a range of 1200--83.9 A, 150 new
lines have been found, the strongest one in a He II line with % - 304 A.
For;these lines an intensity of 15 erg/om2sec has been calculated on. the

earth. Th-is value is incorrect and due to estimations of the effective
absorption cross section of the terrestrial atmosphere other authors
have estimated that at a zenith angle of 79-50 these lines will be
reduced to one eighteenth. Based on known data a new estimation of the
intensity has been done and the value found is % - 1.2 erg/cm 2sec.
The results found with these two lines in two separate tests agree very
well. The effective absorption cross section obtained for this line is
1-1-5-10-1 7 om. this also agrees well with data of other authors.
Finally, the difficulties for calibration of measuring instruments is
mentioned, which are used for rocket -tests. One of the smrest ways to
correct data obtained, is seen in comparing data of ultraviolet solar
radiation, which have their origin in the oorona and the transition zone
between corona and photosphere, with those of other apectral regions,
Then, the author talks about a model which he had constructed earlier
(Ref. 30: G. S. ivanov-Kholodny~r, G. lit. Nikollskiy, Aotr. Zhuzn., 22,
65 (1961)) and which is based on newest data obtained with rockets. This
model is very sensitive to the intensity of short wave emission, and it

confirms the ~.")rrectness of' the estimations mentioned earlior. Therefore,
it can be said that the ultraviolet solar radiation is about
30 erg/cm,23ec (5-10-10 11 quanta/CM2sec) at the boundary of the earth's
atmosphere. The main process of the neutralization in the Ionosphere is
a dissociative recombination of the molecules, the atomic ions change
over into molecular ions. In a column of the atmosphere with 1 CM2
cross section about 3-10 11 - 3.1012 recombination and ionization processes
will take place. There are 1 table and 30 references; 12 Soviet-bloc
and 18 non-Soviet-bloc.
