Abstract: Isochronous mass spectrometry has been applied to neutron-deficient ⁵⁸Ni projectile fragments at the HIRFL-CSR facility in Lanzhou, China. Masses of a series of short-lived T_z=-3/2 nuclides including ⁴¹Ti, ⁴⁵Cr, ⁴⁹Fe, and ⁵³Ni have been measured with a precision of 20–40 keV. The new data enable us to test for the first time the isobaric multiplet mass equation (IMME) in fp-shell nuclei. We observe that the IMME is inconsistent with the generally accepted quadratic form for the A=53, T=3/2 quartet. We perform full space shell model calculations and compare them with the new experimental results.
