__B(p,2_)_He reaction at 163 keV

[摘要] The 11B (p,2a)4 He reaction at a bombarding energy of 163 kev has been studied at Rice to complement the measurement previously made there at energies of a few Mev. Many 2-parameter spectra have been taken, both around the 8 Be* recoil axes and at selected angles away from the recoil axes. Coplanar and non-coplanar cases for the three a-particles have been studied. Preliminary analysis yields results similar to those found previously for the higher bombarding energies. Strong sequential decay through the 8 Be* states is observed with very little or no evidence for direct 3~a decay.
