Nuclear structure of144-150Nd in IBM-1

The level structure of 144-150Nd is analysed taking into account the experimental information available, with respect to the symmetries of IBM-1. The level energies, B(E2) values, and interband B(E2) ratios are compared with available data. The adopted level schemes of 144-150Nd and the varying limitations of the interacting boson model in these isotopes are discussed.
