Ab initio computations of deformed odd-mass nuclei
ORAL
Abstract
Coupled cluster theory has been successful in describing spherical nuclei because of its polynomial scaling in computation and its capability to capture the correlation energy. To calculate the open-shell nuclei, we start from a deformed mean field, and the broken rotational symmetry is restored by angular-momentum projection. In an odd mass nucleus, the unpaired nucleon informs us about single-particle states. We validate our approach in 9Be and 21Ne and calculate rotational bands of odd-mass nuclei in the first island of inversion.
