用Penning阱质谱计ISOLTRAP和一个新的线性Paul阱对（33，34，42，43）Ar进行了质量测量。这种安排使我们能够第一次将潘宁阱质量测量扩展到半衰期低于1秒的核素（33 Ar：T（1/2）= 174 ms）。所有研究的核素的质量精度约为10（-7）（Δ m约为4 keV）。检查了A = 33，T = 3/2四重峰的同量异位多重峰质量方程，发现与普遍接受的二次型不一致。
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 ( 33Ar: T(1/2) = 174 ms). A mass accuracy of about 10(-7) (deltam approximately 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.
