Abstract
In order to test ab initio calculations of light nuclei, we have remeasured lifetimes in using the Doppler shift attenuation method (DSAM) following the reaction at 8 and 10 MeV. The new experiments significantly reduce systematic uncertainties in the DSAM technique. The state at 3.37 MeV has corresponding to a of in broad agreement with many calculations. The state at 5.96 MeV was found to have a of and provides a more discriminating test of nuclear models. New Green’s function Monte Carlo calculations for these states and transitions with a number of Hamiltonians are also reported and compared to experiment.
