Hyperspherical elliptic coordinate treatment of muon transfer from muonic hydrogen to atomic oxygen
Abstract
Quantummechanical calculations of muon transfer between muonic hydrogen and an oxygen nuclei for s waves and collision energies in the range 10^{3} 10^{3} eV are presented. Closecoupling timeindependent Schrödinger equations, written in terms of hyperspherical elliptic coordinates, were integrated along the hyperradius to obtain the partial and total muontransfer probabilities. The results show the expected WignerBethe threshold behavior up to collision energies of the order of 10^{2} eV and pronounced maxima at 10^{2} eV which can be interpreted in terms of crossings between potential energy curves corresponding to the entrance channel state (μp)_{1s}+O and two product channels which asymptotically correlate to p+(Oμ)_{n=5,6}. The population of the final states with different orbital angular momenta is found to be essentially independent of energy in the range considered in this work. This can be attributed to a strong selection rule for the conservation of the quantum number associated with one of the elliptic hyperangles.
