Strengths of analogue resonances in (p,γ) reactions on sulphur isotopes

Absolute strengths of the Esub(p)=588 keV resonance in the 32S(p,γ)33Cl reaction and of the Esub(p)=1 214 keV resonance in the 34S(p,γ)35Cl reaction have been determined as 0.20+-0.04 eV and 9.8+-1.0 eV, respectively. The strength of the Esub(p)=1 542 keV resonance in the 33S(p,γ)34Cl reaction and the Esub(p)=1 887 keV resonance in the 36S(p,γ)37Cl reaction have been obtained as 1.4+-0.2 eV and 22+-3 eV, respectively, by comparison with the Esub(p)=1 214 keV resonance in the 34S(p,γ)35Cl reaction. The total, proton and γ-ray widths of the Jsup(π)=7/2- analogue states in 35Cl and 37Cl at Esub(x)=7.55 and 10.22 MeV, respectively, are given. The γ-ray decay of these isobaric analogue resonances in 343537Cl is discussed. (Auth.)
