C226900100018 (MAGSP) Ions recoiling from the target were separated C226900100019 from the beam and dispersed by the Argonne Fragment C226900100020 Mass Analyzer, which selects recoils according to C226900100021 their mass-to-charge ratio. C226900100022 (PGAC) Parallel-grid avalanche counter was located at C226900100023 the focal plane of the FMA to determine C226900100024 mass-to-charge ratio of the reaction products by C226900100025 their measured horizontal positions. C226900100026 (IOCH) Ions were stopped in an ionization chamber C226900100027 filled with isobutane gas at 13 Torr. The IC was C226900100028 divided into three segments (5, 5, and 20 cm long, C226900100029 respectively) to facilitate particle identification C226900100030 by energy loss (dE) and total energy (E) measurements. C226900100031 INC-SOURCE Excited states in 32Cl nucleus were produced via C226900100032 nuclear reaction 10B(24Mg,2n)32Cl by bombarding 10B C226900100033 target with 24Mg ions. Ions recoiling from the target C226900100034 were separated from the beam and dispersed by the C226900100035 Argonne Fragment Mass Analyzer C226900100036 ANALYSIS Excited states of 32Cl were studied by gamma C226900100037 spectroscopy. The unbound states at 1738.1 and 2130.5 C226900100038 keV in 32Cl correspond to 156 and 549 keV resonances C226900100039 in the 31S(p,gamma)32Cl reaction and their properties C226900100040 dominate the 31S(p,gamma)32Cl reaction rate. Gamma-ray C226900100041 partial widths were inferred based upon properties of C226900100042 mirror states in 32P C226900100043 METHOD (EDE) E-dE method was used for particle identification C226900100044 (COINC) Coincidence between gamma rays and recoil ions C226900100045 was required C226900100046 HISTORY (20170923C) Compiled by S.H.
