Survival probabilities of compound superheavy nuclei towards element 119
To synthesize superheavy element 119 is becoming a highly concerned issue as several experimental projects in major laboratories are being pursued. This work studied the survival probabilities of compound superheavy nuclei after multiple neutron emissions based on microscopic energy dependent fission barriers, demonstrating a significant role of triaxial deformation in decreasing the first fission barriers in the heaviest region. Together with the fusion cross sections by the dinuclear system model, the optimal energy and the residual cross section of 243 Am( 48 Ca, 3 n ) 288 Mc are reproduced. Finally the cross sections and optimal beam energies of 54 Cr+ 243 Am and 50 Ti+ 249 Bk reactions are estimated, providing clues for the synthesis of new elements.
