Observation of large incomplete fusion in 16O + 103Rh system at ≈3–5MeV/nucleon

Incomplete fusion of with 103Rh has been investigated using measurement and analysis of excitation functions. Some pxn/αpxn-channels are found to have contribution from pre-cursor decay, which has been separated out from cumulative cross-section of evaporation residues. The xn/pxn-channels are found to be satisfactorily reproduced with the predictions of PACE4 after subtraction of pre-cursor decay contribution, in general. Sizable enhancement in the experimental cross-sections has been observed for α-emitting channels over the theoretical once, which may be attributed to the incomplete fusion. The percentage fraction of incomplete fusion has also been deduced, which seems to be sensitive for projectile energy, entrance channel mass-asymmetry and/or projectile structure. The present work deals with the competition of incomplete fusion with complete fusion even at ≈3–5MeV/nucleon for 16O + 103Rh system.
