We have studied the fission-neutron emission competition in highly excited ²⁷⁴Hs (Z = 108) (where the
fission barrier is due to shell effects) formed by a hot fusion reaction. Matching cross bombardments
(²⁶Mg + ²⁴⁸Cm and ²⁵Mg + ²⁴⁸Cm) were used to identify the properties of first chance fission of...
Abstract: Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, P[subscript CN], i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and...
