Configuration-mixed-shell-model relative-alpha-decay-rate calculations for spherical doubly odd nuclei (/sup 212/At and /sup 212/At/sup m/)
A brief review of the development of ..cap alpha..-decay-rate theory is given. Then in this paper are presented relative ..cap alpha..-decay-rate theoretical calculations for doubly odd spherical nuclei for /sup 212/At and /sup 212/At/sup m/ ..cap alpha.. decay to excited states of /sup 208/Bi using mixed-configuration-shell-model parent and daughter wave functions and ..cap alpha.. particle approximations. Results are presented for no mixing and for Kim and Rasmussen, Ma and True, and Kuo and Herling wave functions for both the parent and daughter nucleus. The results are compared with the experimental data. There is a great sensitivity to configuration mixing, and no set of wave functions is wholly satisfactory. Stripping and pickup experiments testing the wave functions are reviewed and difficulties noted. It is concluded that ..cap alpha..-decay rates provide a stringent test for the effective shell-model neutron-proton interaction in the lead region. Further theoretical and experimental work is needed.
