Scattering ofμ−Mesons by Nuclei

Previous hand calculations for the scattering of ${\mu }^{-}$ mesons by nuclei have been extended by using a IBM-650 Computer, to include energies corresponding to $\frac{v}{c}=0.2\mathrm{}$ ($E=2.1\mathrm{}$ Mev) and 0.4 ($E=9.6\mathrm{}$ Mev) for the nuclei $Z=48\mathrm{} \mathrm{and} 80$, the nucleus being considered as a uniformly charged sphere of radius $R=1.2\mathrm{}{A}^{\frac{1}{3}}\times {10}^{-13\mathrm{}}$ cm.
