Cadmium ratio measurements were made in similar lattice positions in ZEEP with thin foils of Sm/sup 152/ and gold. From a comparison of these cadmium ratios it is found that 0>i is assumed to be 212 plus or minus 12 barns, then I- = 3100 plus or minus 200 barns. On the assumption that only one resonance in Sm/sup 152/, at 8 ev, contributes appreciably to both the resonance integral and the thermal cross section, it follows that g = 1 and that GAMMA , the width at half-maximum of the total cross section resonance, is 193 plus or minus 5 milli- ev. Because of the appreciable disagreement between this value and one reported earlier, a new time-offlight measurement of the resonance parameters was made. (auth)
