Abstract

The Be9(Li7,p)C15 reaction has been studied at E(Li7)=20 MeV using the Penn multiangle spectrograph. In addition to C*15(0.0, 0.74), proton groups are observed to at least 25 excited states with Ex<12 MeV. Angular distributions are reported for many of these groups. Jπ=(12) and 52 are suggested for the states C*15(3.11) and C*15(4.22), respectively. It is concluded from the small reduced width for neutron decay of suggested 2p-1h neutron states in C15 that the C15(g.s.) has only a small 2p-2h neutron component.

NUCLEAR STRUCTURE Be9(Li7,p), E=20 MeV; measured σ(θ), Γ. C15 levels deduced J, π. Calculated Γn deduced ln, S. Resolution 35 keV: θ=3.75168.75°; Δθ=7.5°.
