Quadrupole dynamics of carbon isotopes and 10Be

Autor: Li, H., Fang, D., Ong, H. J., Shirokov, A. M., Vary, J. P., Yin, P., Zhao, X.

Electric quadrupole (E2) moments and transitions provide measures of nuclear deformation and related collective structure. However, matrix elements of the E2 operator are sensitive to the nuclear wave function at large distances and are poorly conver
