摘要：

Proton capture resonances in 30Si(p, γ)31P were studied in the energy range Ep = 2-3 MeV. The gamma-ray decay of 26 resonances were investigated with a 10 cm3 Ge(Li) detector. Unique spins for 22 of these resonance levels were found from double and triple angular correlation measurements with NaI(Tl) detectors. The resonance at Ep = 2698 keV was shown to be a doublet with spins 9 2 and 3 2. A new bound state is proposed at Ex = 6507±2 keV. The quadrupole/dipole mixing ratios for the 1.27 → 0 and 4.19 → 1.27 MeV transitions, were found to be 0.31±0.01 and 0.10±0.03, respectively. © 1968.
