Abstract

A search has been made for a resonance in the

{}^{2}H {(α, γ)}^{6} Li

capture-reaction cross section at the energy corresponding to the

0^{+}

,

T = 1

, 3.56-MeV state of

{}^{6}{Li}

. None was found, and an upper limit of 6.5×

10^{- 7}

eV was set on the parity-forbidden

α

width at the 90% confidence level. This limit is three orders of magnitude smaller than the best previous measurement.
