Isovector radiative decays and second-class currents in mass 8 nuclei
Journal Article

· Phys. Rev., C; (United States)
The total isovector M1 radiative width of the 16.6-16.9 MeV doublet in /sup 8/Be to the broad first excited state has been measured via the /sup 4/He(..cap alpha..,..gamma..) reaction to be 6.10 +- 0.53 eV. Angular distributions at the 16.6 and 16.9 MeV resonances have been measured and determine the isovector E2 to isovector M1 mixing ratio to be delta((E2,T = 1)/(M1,T = 1)) = 0.19 +- 0.03. A comparison of these results with recent ..beta..-..cap alpha.. angular correlation measurements of /sup 8/Li and /sup 8/B is consistent with predictions of the conserved vector current theory and the absence of a second-class induced tensor form factor.
