Angular Correlation and Polarization Measurements in 214Po using GRETINA

ORAL

Abstract

Nuclei in the neutron-rich region around 208Pb offer a perfect testing ground for realistic shell model interactions, yet experimental data becomes increasingly sparse moving east from the closed shell. The decay of 226Ra offers a simple way to study several neutron-rich A=214 nuclei which are populated in β decays along the decay chain. To study the decay of 214Bi into 214Po, we use GRETINA at NSCL, MSU to assay a source of 226Ra. Despite being a very well studied nucleus, we identify several new transitions and levels populated in the decay. In addition, we performed γ-γ angular correlation and polarization measurements to make definite spin/parity assignments. A revised level scheme will be presented and compared to current shell model calculations.
