Scattering ofμMesons from the Nuclei of Bromine and Silver

Abstract

The $\mu$-meson elastic scattering cross section and polarization asymmetry factor are calculated for bromine for positive and negative muons, and for silver for negative muons, for the values of $\frac{v}{c}=0.4, 0.6, \mathrm{and} 0.7$. These results, when combined with the ones available for cadmium, permit the comparison of theory with measurement of the scattering of muons in emulsions. The nuclei are taken to be extended, with a charge distribution as derived from electron scattering, the Dirac equation is assumed valid, and the calculation is done with the aid of an IBM-650 computer utilizing the same program as used previously for the calculations on cadmium and mercury.
