In this paper, the negative parity low-spin states of even–odd 187–197 Pt isotopes have been studied within the framework of the Interacting Boson–Fermion Model (IBFM-1). The single fermion is assumed to be in one of the 2 f 5 / 2 , 3 p 3 / 2 and 3 p 1 / 2 single-particle orbits. The calculated negative parity low-states energy spectra agree quite well with the experimental data. The B ( E 2 ) values have been also calculated and compared with the experimental data. The calculated energy levels and B ( E 2 ) are in good agreement with experimental data than that in the previous study for 195 Pt isotope. Furthermore, the energy levels, electric quadrupole transition probabilities and the potential energy surface for even–even platinum isotopes (as core for even–odd nuclei) have been calculated within framework of the Interacting Boson Model (IBM-1). The predicted energy levels and B ( E 2 ) transition probabilities results are reasonably consistent with the experimental data. The contour plot of the potential energy surfaces shows all interesting nuclei are deformed and have γ -unstable-like characters. [ABSTRACT FROM AUTHOR] |
