【 摘 要 】

The asymmetric cluster states in28Si are discussed on the basis of antisymmetrized molecular dynamics. It is found that the inversion doublet bands having the24Mg+α,20Ne+8Be and16O+12C cluster configurations appear in the energy range of Ex= 10 ∼ 15 MeV. It is demonstrated that the24Mg+α,20Ne+8Be cluster states have pronounced isoscalar monopole (IS0) and dipole (IS1) transition strengths from the ground state. This result suggests that the IS0 and IS1 strength are good probe for these cluster states.
