Muon capture in the shell model

[摘要] NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.An effective weak interaction Hamiltonian due to Primakoff has been used in conjunction with the shell model of the nucleus to predict [...] meson capture rates to the bound states of [...], [...] and [...]. All three of these nuclei have a slow inverse [...] decay which should permit detection of a capture by an experiment which is easier than that necessary when the inverse [...] decay is fast. The [...] and [...] capture rates are predictable with sufficient confidence to constitute a test for the presence of the induced pseudoscalar interaction in [...] capture, but are not sufficiently sensitive to the presence of the conserved vector current in the weak interaction to decide on its existence. The [...] predictions are interesting from the point of view of nuclear structure, in that they are an analogue of "allowed but unfavored" transitions in [...] decay theory, and the capture rate is reduced due to the different space symmetries of the states involved. Central values of the predicted capture rates to bound states are, in [...]; [...]; and in [...].
