Two and three fragment decay from Z = 120 isotopes

Abstract : The decay into two and three fragments from superheavy nuclei is studied using the macroscopic-microscopic method to obtain the total deformation energy. The two-center shell model is employed to calculate the level scheme transition from the superheavy parent nucleus to the emitted cluster plus daughter nucleus. The three-center shell model is also used to compute the transition toward three equal fragment partition. The levels are used to compute the shell corrections with the Strutinsky method. The liquid drop part is calculated using the Yukawa-plus-exponential model. The total deformation energy is then minimized over a multidimensional space of deformation. The dynamics is completed with the Werner-Wheeler tensor of inertia calculation, and cluster emission paths for binary and ternary splitting are obtained for Z = 120 isotopes.
