Abstract

In this work, we reconstruct the γ-photon energy spectrum which is in good agreement with the experimental data of ⁸⁶Kr + ¹²C at E/A = 44 MeV in the framework of our modified EQMD model. The directed flow and elliptic flow of free protons and direct photons have been investigated by taking α-clustering structure of ¹²C into account. Comparing with the free proton, the direct photon flows give a clearer information about early stage of nuclear reaction. Difference of collective flows between different configurations of ¹²C is observed in this work. This indicates that collective flows of direct photons are sensitive to the initial configuration, therefore the γ bremsstrahlung process might be taken as an alternative probe to investigate α-clustering structure in light nucleus from heavy ion collisions at Fermi-energy region.
