Muon Absorption by Nuclei withN>Z

Muon absorption is investigated for nuclei with an excess of neutrons in order to answer the question: Are the studies carried out in previous works on $N=Z$ nuclei valid for a larger class of nuclei with $N>Z$ and possibly heavier? If so, to what extent? The present study indicates that the conventional shell-model techniques yield similar results for a more complex class of nuclei. Several selected nuclei are taken as examples; the ${}_{}{}^{88}{}_{}{}^{}\mathrm{Sr}$ nucleus is thoroughly studied.
