Precise γ-ray intensity measurements in 10B.

Precise electromagnetic transition matrix elements in 10Be and 10C have provided surprisingly stringent tests of modern ab initio calculations using realistic nuclear forces. The analog transition in 10B can further constrain these new calculations and probe the symmetry of the wave functions across the A = 10 multiplet. We report on a careful measurement of the β-ray intensities from states populated in the 10B(p,p') reaction at 10 MeV, including a determination of the key E2 branch from the J = 2 T = 1 state at 5164 keV to the J = 0 T = 1 state at 1740 keV of 0.16(4)%.
