Collective excitations of transactinide nuclei in a self-consistent mean field theory

We applied the ATDHFB approach for study of properties of collective quadrupole states in several transactinide nuclei: U-238, Pu-240, Pu-242 Cm-246 Cm-248, Cf-250 and Cf-252. Calculated energies and B(E2) transition probabilities are in a reasonable agreement with experimental data. We present also results concerning superdeformed collective states in the second minimum of potential energy of the Pu-240 nucleus.
