The nuclear structure of Cf produced by the O+Cf multinucleon transfer reaction was investigated using -ray spectroscopy. Analysis of the -ray spectrum of Cf revealed the presence of multiple long-lived (isomeric) excited states at low excitation energies. The energies and half-lives of the isomers contain information on the proton and neutron orbits in the heavy-element region and the deformation of atomic nuclei, and are important data to predict the properties of nuclei in the "island of stability".
