Abstract
Aiming to investigate the incomplete fusion processes at low projectile energies, experiments have been carried out for the 13 C + 169 Tm system at ≈ 4-7 MeV/A. Excitation functions for several heavy residues likely to be populated via complete and incomplete fusion processes have been measured using heavy recoil residue catcher technique followed by γ - ray spectroscopy. The measured cross-sections for the complete fusion (xn and pxn ) channels are compared with the statistical model code PACE4, consistently using the same set of parameters. The complete fusion channels are found to be consistent with the model calculations. However, the cross-sections for all the measured α-emitting channels are found to be significantly enhanced over the calculations. Analysis of data indicate a significant fraction of incomplete fusion even at energies as low as 17% above barrier. The present results are discussed in light of the Morgenstern’s systematics. Incomplete fusion strength function is found to be relatively large for alpha cluster projectile i.e. for 12 C as compared to one neutron excess 13 C projectile.
Highlights
IntroductionEPJ Web of Conferences of these experiments suggested that the process involved in the production of fast-α-particles is the projectile break-up (BU), in the nuclear field of the target nucleus
The SUMRULE model of Wilczynski et al.[10], considers that incomplete fusion (ICF) processes mainly originate from peripheral interactions and they are localized in the angular momentum space above the critical angular momentum for the complete fusion (CF)
The excitation functions (EFs) of individual reaction channels populated in 13C+169Tm system at energies ≈ 4– 7 MeV/nucleon have been measured and analyzed within the framework of statistical model to look for the influence of ICF in light of Morgenstern’s mass asymmetry systematics [13]
Summary
EPJ Web of Conferences of these experiments suggested that the process involved in the production of fast-α-particles is the projectile break-up (BU), in the nuclear field of the target nucleus. High quality data on excitation functions (EFs) [3,4], spin distributions (SDs) [11], and linear momentum distributions [12] of individual reaction products have been obtained at the IUAC, New Delhi in a variety of experiments. These studies conclusively demonstrate the low energy ICF but limited only for a few projectile-target combinations. The EFs of individual reaction channels populated in 13C+169Tm system at energies ≈ 4– 7 MeV/nucleon have been measured and analyzed within the framework of statistical model to look for the influence of ICF in light of Morgenstern’s mass asymmetry systematics [13]
