Estimates of production and structure of nuclei with Z = 119

Abstract

The comparative analysis of the hot fusion reactions Ti50+247−249Bk and V51+246−248Cm for synthesis of element 119 is made with the dinuclear system model and the prediction of nuclear properties of the microscopic–macroscopic approach, where the closed proton shell at Z≥120 is expected. The quasiparticle structures of nuclei in the α-decay chain of 295119 and a possible spread of alpha energies are studied. The calculated values of Qα are compared with available experimental data. The termination of the α-decay chain of 295119 is revealed.
