Verification of the space-star anomaly in nd breakup

Abstract

Cross-section measurements of a collinear configuration, the space-star and the coplanar-star configurations in nd breakup at En = 13.0 MeV are reported. The present measurements for the collinear configuration are in good agreement with pd and nd data. Our coplanar-star data are consistent with theoretical predictions and resolve the reported problem with this configuration. The previously observed large discrepancy between theory and nd cross-section data for the space-star configuration is confirmed in the present work.
