Abstract

Employing a 2.5 curie 137Cs source, total elastic scattering cross sections in Pb, Pt, Ta, Sn and Zr were determined using a collimator geometry similar to that of Wilson at angles 20°, 30°, 45°, 60°, 75° and 90°. The experimental results were compared with theoretical values obtained from the form-factor formula of Bethe and exact calculations of Brown et al. The experimental values in Pb, Pt and Ta are in conformity with the theoretical values calculated from Brown et al. data. The experimental values in Sn and Zr show good agreement with form-factor values.
