In the OM calculation, the double folding procedure using the realistic CDM3Y3 effective nucleon-nucleon (NN) interactions and the wave functions of colliding nuclei is employed to describe the nucleusnucleus potential at low energy region below 10 MeV per nucleon. The obtained results from the elastic scattering analyses show that the adiabatic density approximation is more reasonable than the frozen density approximation to describe the overlapping density (the so-called nuclear medium) for the 12C + 12C system at low energy region. | TAÏP CHÍ PHAÙT TRIEÅN KH&CN, TAÄP 20, SOÁ T2- 2017 Study of the nuclear medium by 12C + 12C elastic scattering analysis at low energy region Le Hoang Chien University of Science, VNU-HCM Institute for Nuclear Science and Technology Do Cong Cuong Nguyen Hoang Phuc Dao Tien Khoa Institute for Nuclear Science and Technology (Received on 29th November 2016, accepted on 23th May 2017) ABSTRACT nuclei is employed to describe the nucleusThe nuclear medium is investigated by nucleus potential at low energy region below studying the 12C + 12C elastic scattering at the 10 MeV per nucleon.

CDM3Y3 effective nucleon-nucleon (NN) interactions and the wave functions of colliding Key words: elastic scattering, Optical Model, adiabatic approximation INTRODUCTION The 12C + 12C reaction is an interesting topic that has attracted many researches in both the experimental and theoretical fields over four decades. There are many studies in the experimental field to measure the data over a wide range of energies [1–7], which are analysed theoretically by employing both the phenomenological and microscopic potentials [8– 11]. The experimental data of angular distributions corresponding to the region of energies above 10 MeV per nucleon have been studied and explained unambiguously using the optical potential with the deep real part [8]. However, in the energy region below 10 MeV per nucleon, the experimental data have not been analysed clearly, .
