Alpha Spectrum in theLi7(p, γ)Be8*(α)He4Reaction

The alpha-particle spectrum in the ${\mathrm{Li}}^7(p, \gamma ){\mathrm{Be}}^{8*}\left(\alpha \right){\mathrm{He}}^4$ reaction was observed with magnetic analysis from 1.0-5.5 Mev, corresponding to excitation energies in ${\mathrm{Be}}^8$ from 2-11 Mev. In addition to the well-known structure at $E_{\mathrm{ex}}=2.9\mathrm{}$ Mev, very broad structure in the region of $E_{\mathrm{ex}}=10\mathrm{}$ Mev was observed. No evidence was obtained for the existence of levels between 3 and 10 Mev.
