Abstract

High-angular-momentum states in $^{108} Cd$ were populated via the $^{64} Ni (^{48} Ca, 4 n)$ reaction at a beam energy of 207 MeV. Gamma rays were detected using the Gammasphere array. A rotational band has been observed with a dynamic moment of inertia and deduced lower limit of the quadrupole moment suggesting a major-to-minor axis ratio larger than 1.8:1, placing it among the most deformed structures identified in any nucleus, to date.
