Energy and Angle Distributions for Atmospheric and Cosmic Diffuse Gamma Rays from 2 TO 25 Mev.
Abstract
A double Compton scatter gamma ray telescope flown on a balloon to 3.0 g/sq cm residual atmosphere was used to measure angle and energy distributions for gamma rays near the top and deep within the atmosphere for energies of 2 MeV to 25 MeV and zenith angles of 0 deg to 50 deg (downward moving) and 130 deg to 180 deg (upward moving) and the cosmic diffuse flux of gamma rays for energies from 2 MeV to 25 MeV. Growth curves from 3.4 to 100 g/sq cm of residual atmosphere are used to determine the downward moving atmospheric fluxes above the Pfotzer maximum. Results are given for six energy intervals and for five angle intervals.
