  The isovector giant dipole resonance (IVGDR) in even-even Nd isotopes from
A=124 to A=160 is studied in the framework of time-dependent Hartree-Fock
(TDHF) with Skyrme forces SkI3, SVbas, SLy5 and SLy6. The dipole strength is
calculated and compared with the experimental data on photon absorption cross
section $\sigma_{\gamma}$. An overall agreement between them is obtained. The
dipole strengths in $ ^{124-140}\text{Nd}$ and $^{152-160}\text{Nd} $ are
predicted. In addition, the correlation between the quadrupole deformation
parameter $\beta_{2}$ and the splitting $\Delta E/ \bar{E}_{m}$ of the giant
dipole resonance (GDR) spectra is studied. The results confirm that $\Delta E/
\bar{E}_{m}$ is proportional to $\beta_{2}$. Shape phase transition in Nd
isotopes is also investigated in the light of IVGDR.
