INCOMPLETE FUSION IN THE EXCITATION FUNCTIONS OF 12C + 115In REACTIONS AT 4–7 MeV/NUCLEON

“…[2][3][4][5] It was observed by several investigators [6][7][8][9][10][11][12][13][14] that the onset of the ICF mechanism, particularly in the medium mass region occurs just above the Coulomb barrier. Bindu Kumar et al 6,7 have attributed the ICF to the peripheral collision between projectile-target collisions.…”

“…In most of the reactions studied the binary breakup of the compound nucleus (CN) is seen as either a fusionfission (FF) [1,2] or a deep-inelastic (DI) orbiting [3] process. The large-angle orbiting yields are found to be particularly strong in the 28 Si + 12 C reaction [4], as illustrated by Fig. 1 which summarizes some of the experimental results that have been collected for this system; i.e., orbiting cross sections [4,5] and total evaporation residue (ER) cross sections [6][7][8][9][10][11][12].…”

However, FF calculations [1] significantly underpredict the cross sections measured in the carbon channel by almost a factor of 3, thus suggesting an alternative mechanism (see Fig.…”
