K. Zhao et al., MEASUREMENT OF THE SM-158 MASS EXCESS BY THE (O-18, NE-20) REACTION, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 357(1), 1997, pp. 75-77
A Q-value of 4.046 +/- 0.102 MeV has been determined for the two proto
ns transfer reaction Gd-160(O-18, Ne-20)Sm-158 at 98.95 MeV. This resu
lt yields a first experimental measured value of -65.738 +/- 0.102 MeV
for the mass excess of Sm-158, the nucleus far from stability. The re
sult is compared with current theoretical predictions.
