摘要：
The inclusive process of the neutrinoless muon-to-electron conversion in nuclei is investigated by using the renormalized quasiparticle random-phase approximation (RQRPA). This approach is an improvement of the ordinary QRPA which restores the Pauli principle. It is a more reliable method for extremely small transition matrix elements as for the (mu(-),e(-)) conversion. Our calculations refer to a set of nuclei throughout the periodic table but we specifically investigate those isotopes for which experiments are done or planned. We study in particular Ti-48 which is at present used as a target at PSI in the new ongoing mu-e conversion experiment with the SINDRUM LI spectrometer. (C) 2000 Elsevier Science B.V.
