“…Since the mass number of residue 24Na is very close to mass of the target 27A1, the production of residues 24Na are due to the direct reaction mechanism by stripping of two protons and one neutron from the target nucleus as pointed out by Landenbauer-Bellis et al [25]. The SUMRULE model predictions for the present system concludes that ICF is associated even at smaller values than that of the critical value of the angular momentum for CF process.…”

“…The observed enhance ment by several orders of magnitude over their negligible theoretical predictions for this channel and no conclusive trend of EFs may be attributed to the fact that the residues 24Na are not likely to be populated by CF and ICF processes but via the direct reaction mechanism. Landenbauer-Bellis et al [25] have also indicated the production of the residues 24Na by the direct reaction process.…”

“…[25], present measurements, most of the CF residues produced were either stable or very short lived and could not be detected because of the limitation of the technique used, while pace4 calculations for CF (xn and pxn) channels gave satisfactory reproduction of the experimental data [3,[7][8][9][10]23,31], Thus, the calculated CF yields from the code PACE4 are taken into account for comparison purposes to determine ICF yields for a-emitting channels. The calculated EFs for some dominant reaction channels and total fusion cross sections obtained from PACE4 code are shown in Fig.…”

Background:The reaction mechanism in the low mass region particularly at low projectile energies in heavy-ion fusion processes has not been fully understood. More and more experimental data on fusion processes are required for the accurate description of reaction processes involved at low projectile energies. In the literature, cross section data for the fusion process using a l2C beam in the lower mass region and at low projectile energies are scarce. Purpose: To understand the dynamics of fusion processes and to test various existing theoretical models, the measurements of reaction cross sections in the l2C + 27AI system have been carried out. Method:The experiments were performed for the measurement of the cross sections for the residues produced in the interaction of the l2C ion with a 27A1 target nucleus at 20 different energies covering the energy range from «^39 to 85 MeV. The off-line y-ray spectrometry based activation technique has been used to measure the cross sections. Results: The measured excitation functions were compared to those evaluated with the code p a c e 4 based on the statistical approach and Monte Carlo procedure. The enhancement of experimental cross sections as compared to the theoretical predictions of code PACE4 has been observed. The SUMRULE model predictions indicate that incomplete fusion processes are associated with smaller values of the angular momenta than that of its critical value required for complete fusion processes. Conclusions: In the lower mass region, phenomena such as incomplete fusion and direct reaction processes are of importance even at energies as low as « 3 -7 MeV/nucleon, where fusion evaporation channels are expected to be dominant.
