【 摘 要 】

The isoscalar monopole and dipole transitions and their relationship to the clustering are discussed. By exploiting the Bayman-Bohr theorem, analytical formulae for the transition matrices are derived to show that the cluster states are very strongly populated by the IS monopole and dipole transitions. For the quantitative discussion, the AMD calculations for20Ne,44Ti and24Mg are presented. It is demonstrated that IS monopole and dipole transitions are excellent probe for the clustering.
