Description

A preliminary result was reported for the experiment to determine the mass of the heavier neutron-rich nucleus 158Sm using the 160Gd(18O,20Ne) two proton transfer reaction in last progress report. The average Q-value of (4.046 +- 0.102) MeV for the 160Gd(18O, 20Ne)158Sm reaction is given. A mass excess for 158Sm of (-65.738 +- 0.102) MeV was derived. This is the first experimentally measured value of the mass of 158Sm which is about 450 keV higher than the evaluation value from systematic trends listed in the 1993 atomic mass table. The new prediction shows better agreement with the measured values and a significant improvement over the earlier FRDM (finite-range droplet model) value
