Abstract
Extensive penetrating cosmic-ray showers were recorded with an arrangement consisting of a penetrating shower set
P
and an extension
E
containing shielded and unshielded counters. The following results were obtained: (1) The effective density integral spectrum of the showers observed is given by
D
(
x
) =
Ax
-0.5
, where
x
is the number of particles per m.
2
. (2) The rate of shower coincidences decreases only slightly when the extension is moved from a distance of 0.5 m. to a distance of 9 m. from the main set
P
. (3) The ratio of the coincidences obtained with shielded and unshielded extension counters does not change noticeably with increasing separation between
E
and
P
. The results are based on approximately 10,000 hr. of recording.
