HIGH ENERGY COSMIC GAMMA RADIATION,
Abstract
A sequence of ten balloon-borne experiments was designed to detect gamma rays by conversion in lead. The counter telescopes were sensitive to radiation from directions near zenith; nominal acceptance cones of 10 degrees, 30 degrees, and 60 degrees have been used. Seven of the flights produced useful data at high altitude, with results in three classes: i) an isotropic background flux of at least .0006 gamma/sq cm -sec-ster which may be of primary origin; ii) an anomalous flux from 20 hr. right ascension and +30 degrees declination, with an intensity of at least .0002 gamma/sq cm-sec; and iii) several short time variations of gamma ray and charged particle fluxes. There is as yet no explanation for the time variations, but similar effects have recently been reported from another experiment at lower energy. (Author)
