The nuclear structure of 225Ra

The level structure of 225 Ra has been studied using the (d, t) reaction with both unpolarised and polarised deuterons and the β − decay of 225 Fr. Cross sections and excitation energies have been measured for 41 levels below 1800 keV in the (d, t) reaction, and levels up to 724 keV have been established from the β − decay measurements. The level structure is interpreted in terms of the Nilsson model.
