NUCLEAR THEORY AND PARTICLE PHYSICS
I. RESEARCH INTERESTS
Nuclear reaction: The nuclear reactions with a wide range of bombarding energies are researched by using the quantum scattering theory, the optical model, the folding model, the distorted wave Born approximation (DWBA), the coupled channel method (CC) and the classical approximations,… In detail:
+ Research in the elastic scattering processes in the medium and high ranges of energies to compare and explain the experimental data.
+ Study on the nuclear reactions such as transfer reactions, fusion reactions at very low energies which are typical for astrophysics interest. With the obtained results, we explain and evaluate the nuclear evolution in stars.
Nuclear structure: The shell model, the Fermi model and liquid drop model are studied and employed for exploration of the nuclear structure. In particular:
+ Study about the nuclear forces.
+ Calculate the energy levels of nucleons and the general characteristics of nuclei at far away the valley of stability.
Elementary particle theory: We are interested in studying the most fundamental questions about nature, such as: what is the source of particles’ masses, quantum theory of gravitation, the asymmetry of matter and antimatter in nature, etc. In the meantime, we are interested in experimental techniques in high energy physics performed at colliders such as the Large Hadron Collider and KEK. Our group also focuses on simulating the interactions of fundamental particles and analyzing experimental data in high energy physics. Specifically:
+ Research in the neutrinoless double beta decay of 48Ca.
+ Study of the jet quenching from Z+jet production in heavy ion collisions.
+ Study of muon-electron conversion, and Charged Lepton Flavor Violation process.
II. RESULTS
The reaction cross section of 4He from the optical model calculations
The elastic scattering data of the 12C + 12C reaction are measured in the energy range of 6 to 10 MeV* in comparison with the Optical Model (OM) and Couple Channel (CC) results. (*): Phys. Rev. C 22, 2462 (1980).
The shape of nuclei are obtained from monopole, dipole and quadrupole transitions
