Abstract:The mass excess of the147Gd nucleus was measured from the144Sm(12C,9Be)147Gd reaction using the 72 MeV12C beam of the Orsay MP Tandem and the “Bacchus” magnetic spectrometer. The measurement is auto-calibrated by the10Be spectrum from the144Sm(12C,10Be) reaction. The derived value of the mass excess of147Gd is ?75.401±0.025 MeV. It is compared with other recent results and with calculated values.
