A STUDY OF COMPLETEAND INCOMPLETE REACTIONS IN OF 12C +169TM SYSTEM AT ENERGY RANGE ≈ 3.6–7.5 MEV/NUCLEON

Abstract

Excitation functions of ¹⁶⁹Tm( 12 C, 4n) ¹⁷⁷Re, ¹⁶⁹Tm( ¹²C, 5n) ¹⁷⁶Re, ¹⁶⁹Tm( ¹²C, n) ¹⁷⁶Ta , 169 Tm( ¹²C, 2n) ¹⁷⁵Ta , ¹⁶⁹Tm( 12 C, 3n) ¹⁷⁴Ta , ¹⁶⁹Tm( ¹²C, 4n) ¹⁷³Ta , and ¹⁶⁹Tm( ¹²C, 22n) ¹⁷¹Lu reaction channels populated in the interaction of ¹²C projectile with ¹⁶⁹Tm target were considered in order to investigate the mechanisms of complete and incomplete fusion reactions. The theoretically predicted excitation functions using PACE4 code were compared with the previously measured excitation functions. For non–α emitting channels cross-section values predicted by PACE 4 in general were found to be in good agreement with the experimentally measured values. However, for α-emitting channels the measured cross-section values were found to be higher than the values predicted by PACE4. The observed disagreement may be credited to projectile break-up in the vicinity of n-n interaction.
