Description
Summary:A recent calculation by Wycech has reproduced the experimental data on the relative two-nucleon absorption rates for K − mesic atoms of deuterium and heavy nuclei despite conclusions to the contrary from earlier calculations and qualitative arguments. In this paper we compare these earlier calculations and arguments with the more recent one and show where the differences arise. We conclude that even the latter calculations contain doubtful approximations but that the conclusions obtained there are correct. Thus any discrepancy between theory and experiment is not of the order of twenty as previously supposed but rather an order of magnitude less than this figure and in consequence there is no evidence for alpha-particle clusters in the nuclear surface as proposed by Wilkinson.
