  Knowledge of the gamma-ray branching ratios of the 7.12-MeV state of 16O is
important for the extrapolation of the 12C(a,g)16O cross section to
astrophysical energies. Ground state transitions provide most of the
12C(a,g)16O total cross section while cascade transitions have contributions of
the order of 10-20%. Determining the 7.12-MeV branching ratio will result in a
better extrapolation of the cascade and E2 ground state cross section to low
energies. We report here on measurements on the branching ratio of the 7.12-MeV
level in 16O.
