Light fragment preformation in cold fission of 282Cn

Regular Article - Theoretical Physics

Abstract.

In a previous article, published in Phys. Rev. C 94, 014309 (2016), we have shown for the first time that the best dynamical trajectory during the deformation toward fission of the superheavy nucleus 286Fl is a linearly increasing radius of the light fragment, \( R_2\). This macroscopic-microscopic result reminds us about the \(\alpha\) or cluster preformation at the nuclear surface, assumed already in 1928, and proved microscopically many times. This time we give more detailed arguments for the nucleus 282Cn. Also similar figures are presented for heavy nuclei 240Pu and 252 Cf. The deep minimum of the total deformation energy near the surface is shown for the first time as a strong argument for cluster preformation.
