Deformation of C isotopes
Y. Kanada-En'yo
Abstract
Systematic analysis of the deformations of proton and neutron densities in even-even C isotopes was done based on the method of antisymmetrized molecular dynamics. The E2 transition strength was discussed in relation to the deformation. We analyze the B(E2;2+1 0+1) in 16C, which has been recently measured to be abnormally small. The results suggest the difference of the deformations between proton and neutron densities in the neutron-rich C isotopes. It was found that stable proton structure in C isotopes plays an important role in the enhancement the neutron skin structure as well as in the systematics of B(E2) in the neutron-rich C.
