[en] A new supersymmetric scheme has been tested against two previously proposed schemes using data of six platinum isotopes. This new scheme is at least an order of magnitude better, in the least squares sense, than the previous schemes. In this new model, the lack of fit is due almost entirely to the lack of fit for the even isotopes. The fitted parameters show a smooth variation over the platinum isotopes studied
[en] A simple semi-empirical model based on the vibrational model is used to investigate the yrast bands of 178-188Pt and '182-198Hg isotopes. Additionally, the model overcomes the effect of the shape coexistence and shape transitions. This model gives a good fit to the observed small spacing between the 10+ and 12+ levels of 1'90Pt and the closely spaced triplet (8+, 10+ and 12+) structure in the energy spectra of 188-198Hg isotopes as compared with the other main models.
[en] The shape of platinum isotopes is considered. Microscopic calculations of the potential energy surface contradict suggestions that these nuclei should be triaxial. The proof of resolving of the platinum isotopes structure using results of Coulomb excitation is made. (S.B.)
[en] The neutron induced reaction cross section of eleven stable isotopes of Platinum and Osmium i.e. 192Pt(n,α)189Os, 194Pt(n,α)191Os, 195Pt(n,α)192Os, 196Pt(n,α)193Os, 198Pt(n,α)195Os 184Os(n,α)181W, 187Os(n,α)184W, 188Os(n,α)185W, 189Os(n,α)186W, 190Os(n,α)187W and 192Os(n,α)189W have been calculated by using software TALYS 1.4 in the energy range between 13MeV to 15MeV. The present situation of (n, α) reaction cross section data for the energy region just below and above the 14MeV threshold region is important for reactor technology but as of now it is still extremely little and discrepant. Thus, the precise cross- sections of all kinds of nuclear reactions are very important and necessary. The result obtained has been compared with several experimental values taken from EXFOR data file and the updated evaluated data file of ROSFOND-2010, JEFF-3.2 and JENDL-4.0. (author)
