Abstract
The (, ) and (, ) reactions have been employed at detection angles near 8° on gas targets of and to produce and measure the masses of the nuclei , , and . The (, ) reactions were performed at an incident energy of 117 MeV and the (, ) reaction at 88 and 75 MeV. The mass excesses of , , and were determined to be 23.92±0.08, 16.67±0.18, and 32.10±0.12 MeV, respectively. Estimated ground state decay widths were MeV, for , , and , respectively. A coefficient of 8±5 keV is indicated for the isobaric multiplet mass equation description of the mass 16 multiplet. Consideration of the possible decay mechanisms of and indicates that both nuclei probably have an appreciable diproton decay width.
NUCLEAR REACTIONS (, ), (, ), (, ). Measured reaction values, ground state deduced mass excesses. Deduced coefficients for IMME. Discuss diproton decay widths.
