| Abstract: | The 4He(3He, n)6Be reaction has been investigated at 36.20 MeV bombarding energy in search for a narrow resonance near the 3He-3He threshold which has been proposed as a possible explanation for the missing solar neutrinos in Davis' experiment. Neutrons have been detected at θb = 0° with an effective resolution < 25 keV in the c.m. system, in coincidence with protons emitted at θp = 50°. No indication for the existence of such a resonance has been found and an upper limit (dσ/dω)res ≦ 7.5 μb/sr has been established. |
