The width of the 5.11 MeV state in 10B and isovector parity mixing

Abstract

We review estimates for effects of parity mixing on the α-capture of vector polarized 6Li to the 5.16 MeV, 2 +, T = 1 state in 10B. The cross section depends on the 6Li polarization direction because of isovector parity mixing with the 5.11 MeV, 2 −, T = 0 state. The effect is enhanced due to isospin conservation. The α-width of the 5.11 MeV state, an important parameter for calculating the enhancement, has been measured to be 0.98 ± 0.07 keV. The consequences of parity mixing are reevaluated using best available values for the relevant parameters.
