In the present work, the clustering effects on the reaction dynamics of compound systems 24,25Mg* formed via respective entrance channels C-12 +(12) C and C-13 +(12) C are studied within the collective clus-terization approach using the dynamical cluster decay model (DCM). Except experimentally observed 6,7Li and 7,8,9Be fragments we have also studied 5He, B-10,B-11 and C-11,C-12 fragments. We have explored, firstly the effect of pairing coefficient and results shown the minute change in clustering effects due to its inclusion or non-inclusion, as the change in pairing energy coefficient at the given temperature of the reaction is not much significant. We see the enhancement in preformation probability of the fragments having the alpha-cluster structure in their complementary fragments. Secondly, the role of level density parameter has been investigated for both the spherical and deformed configurations. It is found that by changing level density parameter if there is enhancement in .& POUND;-summed up preformation probability of a particular fragment then there is decrease in the .& POUND;-summed up penetrability of the same fragment and vice versa, which accordingly affects the yields of the respective fragments. The DCM calculated cross sections follow the trend of ex-perimental observations. The experimentally observed 6,7Li and 7,8,9Be fragments having complementary fragments 18F and 16,18O i.e. having alpha-cluster structure contributes more towards the yield as compared to fragments with absence of alpha-cluster.(C) 2021 Elsevier B.V.
