Abstract
The neutron capture cross sections of the stable neodymium isotopes have been measured with high energy resolution in the keV region at the 40 m station of ORELA. Average resonance parameters are extracted for
s-wave resonances. Significant positive correlations are found between T0n and Tγ all isotopes. The magnitude of the observed correlation coefficient, particularly for 142Nd (p = 0.9), cannot be explained in terms of valence neutron capture and additional mechanisms are discussed. The average s-wave radiative widths for the odd-A isotopes are markedly greater than for the even-A isotopes, while the p-wave radiative
width for 142Nd is considerably less than the s-wave width.
