The ground state mass of /sup 147/Gd from single-neutron transfer reactions

Conference ·
OSTI ID:6853883
Thin targets of radioactive /sup 148/Gd were used to determine a precise value for the mass of /sup 147/Gd. The (p,d), (d,t), and /sup 3/He,..cap alpha..) reactions were used with high-resolution charged-particle spectrometry to determine Q-values for the /sup 148/Gd target relative to several calibration targets having known Q-values. By combining the measured Q-value with the /sup 148/Gd mass, the mass defect, ..delta..M(/sup 147/Gd) = 75356 +- 6 keV, 149 keV less than the value in the 1977 mass tabulation was obtained. 7 refs., 1 fig., 1 tab.
