Description

We produced the lowest T=2 state in 32S with the 31P(p,γ) reaction and measured the energies of the deexcitation γ rays, obtaining an excitation energy of 12047.96±0.28 keV that disagrees with a previous value of 12045.0±0.4 keV. Our result, together with a recent measurement of the 32Ar mass, makes the A=32 multiplet the most precisely measured T=2 quintet and provides easily the most stringent test of the isobaric multiplet mass equation. A significant violation of the isobaric multiplet mass equation is observed that could be explained by mixing with a nearby T=0 level
