摘要: Abstract The 30 Si (α, n γ) 33 S reaction was used to investigate 33S levels up 4.3 MeV excitation energy. Each individual state populated in turn with bombarding energies chosen be sufficiently near threshold that neutrons of low-order angular momentum were emitted. Accurate determined. distributions γ-rays de-exciting these analyzed according standard angular-correlation theory. Experimental results include the spin limitations: J π (2969) = 7 2 + , J(4048) 5 or 9 J(4094) ≧ 3 J(4142) . It is concluded there exist two 4.05 energy a separation 5±4 keV. mixing-ratio determinations permit critical comparison recent shell-model calculations experimental data. are reasonably good agreement
