摘　　要：The polarization charges in ^(44,46,48)Ti are studied by the microscopic particle-vibration model and used to investigate the electric quadrupole transitions of the yrast terminating bands.The validity of theThe polarization charges in ^44, 46, 48Ti are studied by the microscopic particle-vibration model and used to investigate the electric quadrupole transitions of the yrast terminating bands. The validity of the common used empirical effective charges in the pf shell model calculations is confirmed. The B（E, I→I-2） and electromagnetic moments are reasonably well reproduced comparing with experimental results. It is found that the globally decreasing B（E2） is accompanied with convergence of valence particles into lf7/z shell when approaching the terminating states.
