Mass of the lowestT=2state inS32: A test of the isobaric multiplet mass equation Academic Article uri icon


  • We produced the lowest T=2 state in S32 with the P31(p,) reaction and measured the energies of the deexcitation rays, obtaining an excitation energy of 12047.960.28 keV that disagrees with a previous value of 12045.00.4 keV. Our result, together with a recent measurement of the Ar32 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. 2006 The American Physical Society.
