Abstract

Knowledge of the ³He(³He,2p)⁴He reaction is important for understanding stellar burning and solar neutrino production. Previous measurements have found a surprisingly large rise in the cross section at low energies that could be due to a low energy resonance in the ³He+³He (⁶Be) system or electron screening. In the ⁶Be nucleus, however, no excited states have been observed above the first ² state at E_x = 1.67 MeV up to 23 MeV, even though several are expected. The d(⁷Be,t)⁶Be reaction has been studied for the first time to search for resonances in the ⁶Be nucleus that may affect our understanding of the ³He( ³He,2p)⁴He reaction. A 100-MeV ⁷Be beam from the Holifield Radioactive Ion Beam Facility (HRIBF) was used to bombard CD ₂ targets, and tritons were detected by the Silicon Detector Array (SIDAR). It appears that a combination of reaction mechanisms is necessary to explain the observed triton energy spectrum.
