Cascade of negative muons in atoms
Abstract
The evolution is studied of a negative muon captured in an atom and the formalism of energy loss associated with the muonic atom. The principal goals are to calculate reliability the muon Xray intensities, given the initial population of the muonic orbits, to invert the problem and deduce the initial distribution from the Xray intensities, to provide a reasonably simple and convenient tool to correlate observations, and finally, to systematize some questions of theoretical interest. The early part of the history of the muon in matter, including the atomic capture and classical phase of the atomic cascade are reviewed. In the quantal treatment of the transition rates, both radiative and electron Auger transitions are considered. In general, multipolarities up to E3 and K, L, and M electronic shells are fully investigated. Multipole radiation is treated in the conventional way and presents no special problems. Magnetic type transitions between states with different principal quantum numbers are shown to be small. The basic results have been computed in terms of elementary functions.
