New procedure to determine the mass-angle correlation of quasifission
Abstract
An innovative procedure to determine the mass-angle distribution of fragments from quasifission is proposed. It is based on the subtraction of the contribution from compound-nucleus fission from the experimental correlation spectrum which is in most cases a mixture of fusion-fission and quasifission. The former is calculated with a four-dimensional dynamical model of fission within the stochastic Langevin theory. The proposed approach is benchmarked using measurements for different entrance channels, ranging from below to above the onset of quasifission, all leading to the same 202Po composite system. The sensitivity of the procedure is evaluated. Its potential for isolating the fragment-mass and emission-angle information pertaining to the sole quasifission process is discussed.
