T015400100011 FACILITY (CYCLO,1USAINU) T015400100012 INC-SPECT Overall energy resolution was better than 600 keV. T015400100013 Better energy resolution (300-keV) was obtained with T015400100014 second target. T015400100015 SAMPLE CaCl2 foil target, enriched to >98% 37Cl, and about T015400100016 90 mg/cm**2 thick, placed between 25-mg/cm**2 Ca foil.T015400100017 The large difference (13.5 MeV) in (p,n) Q-value T015400100018 between the 40Ca and 37Cl nuclei permits a clean T015400100019 observation of low-lying states in 37Ar. T015400100020 A second target, 32.2 mg/cm**2 of CaCl2 with aluminizedT015400100021 mylar as protective layers, was also used to obtain a T015400100022 cross check on the absolute cross section values.

T015400100025 METHOD (TOF) T015400100026 A self-supporting 100 mg/cm2 foil also bombarded at T015400100027 120 MeV under identical experimental conditions, and T015400100028 the 2 spectra after proper normalization were T015400100029 subtracted.
