【 摘 要 】

A formation process of an acceptor center μB induced by negative muon in a diamond crystal is considered in this work. It is shown that the process under consideration could be represented as three consecutive stages: a kinetic stage, connected with a capture of track electrons, a chemical stage, connected with establishing of chemical bounds of the radiation defect with lattice atoms, and a formation phase of the ionized negatively charged acceptor center. Quantitative estimates of characteristic times are obtained for every stage. It is shown that the total time necessary for the acceptor center formation is of the order 10-8s. So this fact should be taken into account when experimental results are interpreted.
