Instanton-motivated study of spontaneous fission of odd-A nuclei

NUCLEAR STRUCTURE ^256,257,260Rf, ²⁶¹Db, ²⁷²Mt; calculated energy surface contour in (β₂₀, β₄₀) plane, in (β₂₀, β₂₂) plane for ²⁷²Mt, neutron levels around the Fermi level, and fission barrier heights for ²⁷²Mt, actions for separate single particle solutions for ²⁷²Mt, and for the collective velocities for ²⁵⁶Rf and ²⁵⁷Rf using instanton-like cranking mass parameter without pairing. Imaginary-time-dependent Schrodinger equation (iTDSE) using Woods-Saxon potential without pairing, and imaginary-time-dependent HFB (iTDHFB) using fixed potential with pairing.

RADIOACTIVITY ²⁵⁸No, ²⁵⁹Lr, ^{254,255,256,257,257m,260}Rf, ²⁶¹Db, ^{258,259,260,261}Sg, ^282,283Cn(SF); calculated half-lives, and fission hindrance factors using iTDSE and iTDHFB methods. Comparison with experimental data.
