Microscopic study of the shape phase transition in the Sm isotopes. Pt. 3

In the previous paper (2) of this series, the Dyson-type non-unitary representation of the self-consistent collective-coordinate method was used for the microscopic analysis of the phase transition from spherical to deformed shape in the Sm isotopes. The coupling effect between collective quadrupole phonon and non-collective phonons with spin J=0, 2 and 4 were taken into account by this method, and numerical calculation has given rather improved energy spectra of the Sm isotopes. Here the E2-transition properties are analysed in the same framework as that in (II) and a clear theoretical evidence of the shape phase transition is obtained. (orig.)
