Abstract
Systematic analysis of the deformations of proton and neutron densities in even-even C isotopes was performed based on a method of antisymmetrized molecular dynamics. transition strengths were discussed in relation to the deformations. We analyzed the in , which has been found to be abnormally small in the recent measurement. The results suggest a difference between proton and neutron shapes in the neutron-rich C isotopes. It was found that the stable proton structure in C isotopes plays an important role in the enhancement of the neutron skin structure as well as in the systematics of in the neutron-rich C.
