Near scission emission peak energies of α particles in heavy-ion fission reactions

Particle emission is a quite useful probe to gain insights about the complex fission dynamics. During the heavy-ion fission, neutron and charged-particle (mainly proton and α-particle) emission takes place from various stages namely from the fissioning compound nucleus (pre-scission) and from the accelerated fission fragments (post-scission). Presented in this paper are measurements of α-particle multiplicity spectra in ¹⁶O + ²³²Th reaction at various relative angles with respect to beam and the fission fragment direction
