Energy levels and electromagnetic transition of ^190–196Pt nuclei

A description of the even–even Pt isotopes for A = 190 to 196 in the framework of the Interacting Boson Model (IBM-1) is carried out. Energy levels, B(E2) and B(M1) values, branching ratios, E2/M1 mixing ratios and Q_J values of the above nuclei have been calculated. The energy levels, B(E2) values and the electric quadrupole moment Q_J results are reasonably consistent with the experimental data. The magnetic dipole is compared with the available experimental data. Furthermore, the calculated results are better than previous studies. (author)
