Investigation of incomplete fusion dynamics at energy 4–8 MeV/nucleon

Li7 -induced reaction on Monat : A study of complete versus incomplete fusion

“…Experimental observations were found to be fairly large compared to both the theoretical calculations throughout the energy window, indicating the production of residues through the ICF process in addition to the CF. is the total theoretical fusion cross section), with increasing projectile energies was observed in the 7 Li+ nat Mo, as shown in Fig 6(d), similar to that observed in case of the α-cluster projectiles [5][6][7][8]. Nevertheless, limitation of the present method includes unobserved α-emitting channels that went unidentified due to the short half-lives of the 12 residual radionuclides, or production of stable isotopes; hence the ICF corresponding to these missing channels could not be determined.…”

“…However, the total fusion (TF) cross section was satisfied by the coupled channel (CC) calculations indicating an insignificant influence of continuum or the transfer channel on TF, whereas, enhancement was observed below the barrier in heavy mass nuclei [1][2][3][4]. Moreover, significant ICF over the CF above the barrier ∼ 4-10 MeV/nucleon in well-bound α-cluster ion induced reactions has also been observed in the α-emitting channels over the past few years [5][6][7][8][9][10]. More experimental investigation is therefore necessary to resolve discrepancies in the dependence of CF-ICF on projectile types at the low incident energies, particularly, for weakly bound nuclei in which breakup yield is more probable in the nuclear force field.…”

“…An increment in the breakup probability of a projectile with the increasing bombarding energy, more ICF in α-cluster nuclei than others and more ICF for larger entrance channel mass asymmetry corresponding to the same relative velocity, significant ICF contribution for l ≤ l crit contrary to the sum rule model, has been observed in 12,13 C induced reactions on 181 Ta, 159 Tb, 169 Tm, 175 Lu [5][6][7][8]. Incomplete fusion fraction (F ICF ), a measure of the relative strength of ICF to the total fusion, was observed independent of target charge (Z t ) [33,34]; however, contrary to that, in Refs [9,35,36] its nature is found almost proportional to charge Z t .…”

“…From the past decade, several efforts were made to study the effects of various entrance channel parameters, like projectile energy and its structure, angular momentum (l) window for ICF, deformation of interacting nuclei, mass asymmetry, α-Q values (Q α ) etc. on the ICF process by the recoil range distribution technique/recoil-catcher activation technique [5][6][7][8][9][10].…”
