Abstract

Mass measurements on

^{33, 34, 42, 43} Ar

were performed using the Penning trap mass spectrometer ISOLTRAP and a newly constructed linear Paul trap. This arrangement allowed us, for the first time, to extend Penning trap mass measurements to nuclides with half-lives below one second (

^{33} Ar

T_{1 / 2} = 174 ms

). A mass accuracy of about

10^{- 7}

(δ m \approx 4 keV)

was achieved for all investigated nuclides. The isobaric multiplet mass equation was checked for the

A = 33

T = 3 / 2

quartet and found to be inconsistent with the generally accepted quadratic form.
