Independent measurement of the Hoyle state β feeding from 12B using Gammasphere
RADIOACTIVITY 12B(β-)[from 2H(11B, p), E=40 MeV from ATLAS-ANL facility]; measured Eγ, Iγ, γγ-coin, γγ(θ) for the Hoyle state using Gammasphere array. 12C; deduced first excited 2+ and 0+ levels, β branching ratio to the Hoyle state in 12C, logft, indication of higher clustering for the Hoyle state as compared to previous results. Comparison with theoretical calculations using antisymmetrized molecular dynamics (AMD), and with previous experimental results.
