Beta-gamma directional correlation in Sb124

摘要: Abstract The directional correlation between the non-unique first-forbidden outer beta group of endpoint energy 2.31 MeV in Sb124 and 0.603 cascade gamma ray Te124 has been measured at twenty six energies. beta-gamma coefficient ϵ ranges from −(0.186±0.016) to −(0.387±0.010) interval 0.95 2.20 MeV. Taking into account existing data on shape correction factor also angular dependence circular polarization ω, relevant decay matrix element ratios have extracted; elements are (in Kotani's notation) x = 0.06±0.05, u 0.15±0.05 Y 1.05±0.15. Absolute values were obtained observed log ft value as |∫ Bij|/R (1.0±0.2) × 10−2, r |/R (7.5±6.4) 10 −4 , i σ (15.5±5.9) α | (7.0±2.1) . experimental ratio ∫ iα/∫ agrees with predictiction conserved vector current theory decay.
