Abstract
The mass of the particle-unstable nuclide has been measured by means of the (, ) reaction, which has an observed cross section of about 5 nb at 76 MeV. The mass excess found is 35.06 ± 0.05 MeV, and the width of the ground state is 290 ± 80 keV. The result for the mass excess is more precise than that obtained in a previous () experiment and confirms that significant higher-order terms must be added to the isobaric multiplet mass equation to describe the mass-8 isobaric quintet.
