Gamma-ray mean lifetimes of transitions 2+→0+ state for even–even nuclei in the range 58≤Z≤100

Abstract

We explored [Formula: see text]-ray mean lifetimes of transitions [Formula: see text] state suggested by earlier researchers such as Grodzins [Phys. Lett. 2 (1962)], Bohr and Mettelson [Mat. Fys. Medd. Dan. Vid. Selsk 27 (1953) 1], Wang’s formula [Chin. J. Phys. 18 (1980) 151], and best global fit formulae [Phys. Rev. C 37 (1988) 805], equations accessible in the literature for nuclei ranging from [Formula: see text]Ce to [Formula: see text]Fm. Also, as compared to other equations accessible in the literature, the standard deviation observed utilizing Grodzins formula with regard to experiments was lower. We also forecasted [Formula: see text]-ray mean lifetimes of transitions [Formula: see text] state and [Formula: see text]-values for nuclei ranging from [Formula: see text]Ce to [Formula: see text]Fm. Around 136 even–even nuclei’s mean lifetimes and [Formula: see text]-values are predicted which are helpful in the Coulomb fission process.
