Compound-Nucleus Decay along the Mass-Asymmetry Coordinate and the Role of the Businaro-Gallone Point

Complex fragment emission at 50 MeV/u: Compound nuclei forever?

“…However, in agreement with an earlier theory [9], complex fragment emission from a compound nucleus has been observed at very small incident energies, below 50 Me V total center-of-mass energy, albeit with very low (submicrobarn) cross-sections [10][11][12]. Furthermore, in a series of experiments starting at this low energy and continuing to 30 MeV/u, it has been verified that the decay of an equilibrated compound nucleus can account for the major production of complex fragments in a process akin to fission [13].…”

Heavy residues from very mass-asymmetric heavy-ion reactions

“…The source velocity, Vsource, is defined as (11) where mi and Vi are the mass and velocity, respectively, of the i-th detected complex fragment. These distributions were used to determine the velocity of the source of the complex 15 fragments.…”

Complex fragment emission at intermediate energies

“…In a series of experiments (3,4,5), we have studied complex fragment production at progressively larger bombarding energies. The energies studied range from 8.4 MeVfu to 50 MeV/u, which is the highest bombarding energy studied at present.…”
