The decay of the highly deformed (HD) band in the nucleus {sup 137}Nd has been studied with the GASP array using the reactions {sup 110}Pd+{sup 30}Si and {sup 123}Sb+{sup 19}F. Four decay paths linking the HD band to the normal-deformed states have been established, which fix {ital I}{sup {pi}}=29/2{sup +} for the lowest state of the HD band lying at {ital E}{sub {ital x}}=4885 keV. The sudden disappearance, at the low spin side, of the HD bands in the {sup 133,135,137}Nd isotopes can be explained by total Routhian surface calculations through a change of the nuclear shape which is microscopically related to the transfer of the valence neutron from a {ital N}=6 to a {ital N}=4 Nilsson orbital.
