Photon Absorption on a Neutron-Proton Pair in 3He and 4He

الأصل · EN

We have developed a phenomenological quasi-deuteron model to describe photodisintegration reactions of ³He and ⁴He at intermediate photon energies, and compared the results with experimental data obtained by TAGX group in which contributions from photon absorption by pn pair were selectively observed. The data can be reproduced reasonably well, however there still remain certain discrepancies between calculated results and data.
