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.
