Description

Intermediate mass fragments (IMFs: 3 ≤ Z ≤ 18) in coincidence with fission-like fragments were measured in the reaction 40Ar + 232Th at Ebeam = 15 - 115 A MeV. Three distinct sources of IMF emission were identified by using the azimuthal angular correlation function among two fission-like fragments and an IMF. Variations of the respective contributions of the three emission modes to the IMF multiplicity with the beam energy were estimated. Pre-fission emission gains dominance in this energy range while the evaporation from the fission-like fragments decreases to the point that its importance becomes comparable to that of simultaneous ternary breakup.
