Population of ground-state rotational bands of superheavy nuclei produced in complete fusion reactions

Abstract

Using the statistical and quantum diffusion approaches, we study the population of ground-state rotational bands of superheavy nuclei produced in the fusion-evaporation reactions ${}^{208}$Pb(${}^{48}$Ca,2$n$)${}^{254}$No, ${}^{206}$Pb(${}^{48}$Ca,2$n$)${}^{252}$No, and ${}^{204}$Hg(${}^{48}$Ca,2$n$)${}^{250}$Fm. By describing the relative intensities of $E2$ transitions between the rotational states, the entry spin distributions of residual nuclei, and the excitation functions for these reactions, the dependence of fission barriers of shell-stabilized nuclei on angular momentum is investigated.
