Abstract
The results of Monte Carlo calculations on the detection and total absorption peak efficiencies of spherical NaI crystals are presented. A method of applying these data to cylindrical well crystals of arbitrary size and well geometry is described and the results are compared with experimental data. The Monte Carlo computations cover the gamma-ray energy range from 200 kev to 2 Mev and crystal radii from 1.5 to 12.0 cm. Histograms are presented of the number of Compton scattering events which a 0.662-Mev gamma ray undergoes in crystals of different sizes.Keywords
