The D(p, gamma ) 3He reaction, where 'D' denotes '2H', is of primary importance in cosmology and nuclear physics since it offers a unique opportunity to test predictions based on the description of nuclear interactions. We present a novel approach to extract the angular distribution of the photons emitted by the D(p, gamma ) 3He reaction inferred from the shape of the experimental gamma spectra. The measurement was performed in the Gran Sasso Laboratories by the LUNA collaboration. By using a HPGe detector faced to an extended deuterium gas target, it was possible to derive the angular distribution in the 30-280 keV kinetic energy range and to compare the results with recent ab initio predictions.

Abstract
The D(p, gamma ) 3He reaction, where 'D' denotes '2H', is of primary importance in cosmology and nuclear physics since it offers a unique opportunity to test predictions based on the description of nuclear interactions. We present a novel approach to extract the angular distribution of the photons emitted by the D(p, gamma ) 3He reaction inferred from the shape of the experimental gamma spectra. The measurement was performed in the Gran Sasso Laboratories by the LUNA collaboration. By using a HPGe detector faced to an extended deuterium gas target, it was possible to derive the angular distribution in the 30-280 keV kinetic energy range and to compare the results with recent ab initio predictions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
