Abstract / Description:Mass measurements on radionuclides along the potassium isotope chain have been performed with the
ISOLTRAP Penning trap mass spectrometer. For 35K (T1/2 = 178 ms) to 46K (T1/2 = 105 s) relative mass
uncertainties of 2 × 10−8 and better have been achieved. The accurate mass determination of 35K (δm = 0.54 keV) has been exploited to test the isobaric multiplet mass equation for the A = 35, T = 3/2 isospin
quartet. The experimental results indicate a deviation from the generally adopted quadratic form.
