“…1(b) the F ICF is found to increase with mass asymmetry (μ) for the 16 targets. As inferred from this figure, the ICF probability is higher for more mass-asymmetric systems, which is in accordance with the Morgenstern mass-asymmetry systematics [19].…”

Abstract. Present work deals with experimental studies of incomplete fusion reaction dynamics using off-line γ-ray spectrometry at energies as low as ≈3-6 MeV/nucleon. Excitation functions for five reaction products populated via complete and/or incomplete fusion processes in 16 O+ 130 Te system have been measured and compared with the predictions of the statistical model code PACE4. A significant enhancement in the measured excitation functions compared to theoretical predictions for α-emitting channels has been observed and is attributed to incomplete fusion processes. The relative strength of incomplete fusion has been found to increase with projectile energy. Results show that incomplete fusion is associated even for angular momenta lesser than the critical angular momentum for complete fusion and also reveals importance of incomplete fusion even at energies as low as ≈3-6 MeV/nucleon.

“…It is well known that above a certain bombarding energy various incomplete-fusion (ICF) reactions occur in parallel creating quite a range of compound nuclei with different masses, momenta and excitation energies. Since we are measuring in normal kinematics (projectile lighter than the target), and asymmetric colliding systems, the contribution of target break-up to the ICF cross section is negligible compared to that one due to projectile break-up [12,13], and the residue velocity will be proportional to the excitation energy deposited into the original compound nucleus. An increase of excitation energy leads to a larger number of statistically evaporated particles producing an increase of the ER mass width.…”

Abstract. The mass dependence of the critical excitation energy above which a hot nucleus does not decay any more by particle evaporation, has been studied in the mass range 75 < A_< 130. The experimental values of the critical excitation energy have been obtained by means of a new integral method based on the analysis of the widths of the evaporation residue mass distributions as a function of the residue velocity. The obtained mass dependence appears to be stronger than expected by various models and a predicted dependence on the Z/A ratio of the decaying nucleus seems to be confirmed.
