Excitation energies of 21+ and 41+ states of neutron-deficient U and Pu isotopes

The microscopic variant of the Grodzins relation and the Quasiparticle Phonon Model are applied to predict the excitation energies of the [Formula: see text] states of neutron-deficient U and Pu isotopes. The P-factor systematics is used to determine the quadrupole deformation of nuclei under consideration. The excitation energies of the [Formula: see text] states are predicted based on the simple universal anharmonic vibrator-type relation.
