Abstract:
The Brueckner theory is applied to the antisymmetrized molecular
dynamics (AMD) of 8Be with the aim of studying
the clustering mechanism on the basis of the realistic nuclear force.
The role of the tensor force in the clustering is investigated
through the analysis of single-particle energies depending on the
single-particle orbits, which change from one-center atomic orbits
to two-center molecular orbits with the development of
the α-α cluster structure. The clustering is
intensified by the suppression of the attractive tensor force role
in the one-center atomic orbits in the shell model structure.
