Abstract

A search for a He3 + He3 resonance just above threshold was made by means of the reaction Li6(He3,t)Be*6 with 46.3-MeV He3. No resonance was found; the c.m. cross section is ≤1.6 μb/sr at 8.4° c.m. This corresponds to an upper limit on the spectroscopic factor for Be*6He3+He3 of 0.0003 to 0.001, depending on the parameters adopted for a distorted-wave Born-approximation calculation. The maximum possible effect of such a resonance on the production of high-energy solar neutrinos is too small to explain the discrepancy between solar-model predictions and the experimental results of Davis et al.

[NUCLEAR REACTIONS: Li6(He3,t), E=46.3 MeV; measured σ(Et,θ=5). Deduced: no He3-He3 resonance in Be6.]
