摘要

In this study,we reconstruct the y-photon energy spectrum,which is in good agreement with the experi-mental data of 86Kr+12C at E/A = 44 MeV within the framework of the modified EQMD model.The directed and elliptic flows of free protons and direct photons were investigated by considering the α-clustering structure of 12C.Compared with free protons,direct photon flows provide clearer information about the early stage of a nuclear reaction.The difference in the collective flows between different configurations of 12C is observed in this study.This indicates that the collective flows of direct photons are sensitive to the initial configuration.Therefore,the γ bremsstrahlung process might be taken as an alter-native probe to investigate the α-clustering structure in a light nucleus from heavy-ion collisions within the Fermi-energy region.
