T$E STRUCTURE OF ANOMALOUSLY WIDE ATMOSP$ERIC
SHOWERS OF COSMIC RADIATION

The results of observations which established the existence of anomalously
wide atmospheric showers were published in 1947 (D. V. Skobel'tsyn, G. T. Zat-
sepin, and V. V. Miller, PY~ys. Rev., 71, 315, 1847; G. T. Zatsepin and V. V.
Miller, ZhETF, 17, 939, 1947)?
Coincidences in a counter system recording these showers at 3860 m can be
observed at distances up to 1,000 m between counters. Repeated experiments
fully confirmed, with good statistical accuracy, the data obtained on the num-
ber of such ahoxera observed ner unit time. From the interpretation which fol-
lowed (D. V. Skobel'tsyn, DAN, Vol LXVII, I+S, 1949; ibid., Vol LXVII~ 255, 1949),
it was considered proven that these showers are a new phenomenon, not covered
by the classical cascade theory of showers,
These results, however, were incorrectly interpreted by some authors (G.
Cocconi, PhyB. Rev., 72, 350, 1948), who drew the exactly opposite conclusion
that our observations somehow gave new confirmation of the cascade theory of
showers (in the region of very high energies, i.e., 1017-101 eV).
Because of this and is view of the ma,~or importance of this problem, this
paper details a method which solves decisively the problem of whether the data
on the structure of these showers can be reconciled with the cascade theory.
The experiments based, on this method are described in the present issue of Dok-
ladi Akademii Nauk in a paper by G. T, Zatsepin, I. L. Rozental', V. P. Zakharov,
N. G. Khrebet, and G. V. Khristiansen. ~he article referred to is not to be
found in this issue
The discussion which follows establishes that 'anomalously wide shovers are
e new phenomenon essentially different from phenomena described by the ordinary
cascade theory.
