摘要：
The low-lying positive and negative parity states of even-even Nd144-154 isotopes are studied using the interacting boson model (IBM). The negative parity states are involved within the IBM model by adding a single angular momentum (L = 3) boson with intrinsic negative parity f-boson to s and d-bosons model space. For these nuclei, the potential energy surfaces V (beta, gamma), transition probability B(E1), B(E2) and B(E3) are calculated. Phase transition from the U(5) limit to the SU(3) limit is observed in the chain and the critical point has been determined for Nd-150 isotope. It is found that the calculated positive and negative parity energy spectra of Nd-isotopes agree well with the experimental data.
