Excitation energies of $2^+_1$ and $4^+_1$ 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 $2^+_1$ 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 $4^+_1$ states are predicted based on the simple universal anharmonic vibrator type relation.
