Title: Precision test of the isobaric multiplet mass equation for the A=32, T=2 quintet

Abstract

Masses of the radionuclides {sup 32,33}Si and {sup 34}P and of the stable nuclides {sup 32}S and {sup 31}P have been measured with the Low Energy Beam and Ion Trap (LEBIT) Penning trap mass spectrometer. Relative mass uncertainties as low as 3x10{sup -9} have been achieved. The measured mass value of {sup 32}Si differs from the literature value by four standard deviations. The precise mass determination of {sup 32}Si and {sup 32}S have been employed to test the validity of the quadratic form of the isobaric multiplet mass equation (IMME) for the most well known A=32, T=2 isospin quintet. The new experimental results indicate a dramatic breakdown of the model.
