Properties of 12Be and 11Be in terms of single-particle motion in deformed potential

Abstract

Inspired by the recent measurement of the B(E2;$0_2^{+}\to 2_1^{+}$) and B(E0;$0_2^{+}\to 0_1^{+}$) values in ${}^{12}$Be, we give an interpretation of available spectroscopic data on both ${}^{12}$Be and ${}^{11}$Be, using a simple model which contains the essential feature of these two nuclei; the presence of weakly-bound neutron(s) in deformed potentials. The agreement of the calculated results with observed data is surprisingly good, including well-known strong E1 transitions in both nuclei.
