Microscopic description of total muon capture rates for even isotopes of Ti, Cr and Fe

Results are presented of microscopic calculations of total muon capture rates Λsub(μc) for even isotopes of Ti, Cr and Fe. The ground-state wavefunctions for these nuclei required in the calculation of Λsub(μc) are generated from the respective prolate and oblate Hartree-Fock solutions. The dependence of Λsub(μc) with respect to the variation of (i) the oscillator size parameter and (ii) the average neutrino momentum is studied. The calculated Λsub(μc) for 48Ti, sup(50,52,54,56)Cr and 56Fe compare well with the corresponding experimental results and are consistently better compared with earlier theoretical results. (author)
