Abstract
Thermal neutron induced charged particle reactions in a radioactive target of37Ar have been studied. Upper limits of the cross-sections for the (n, α) reaction in radioactive targets of109Cd,125, 127Xe, and132Cs have been obtained. The isotopically pure targets were produced at the ISOLDE facility at CERN and irradiated with thermal neutrons at the high flux reactor of the Institute Laue-Langevin in Grenoble. Charged particles from (n, p) and (n, α) reactions in37Ar were observed with cross-sections of 69±14b and 1970 ±330b, respectively. TheQ-values for these reactions were determined to be 1600 ±12 keV and 4630±7 keV, in agreement with existing mass data. The branching ratio Γα/Γp of the37Ar capturing state was found to be 28.5±2.7. An upper limit of the cross-section for the (n, γα) reaction in37Ar was obtained.
