Isochronous mass spectrometry has been applied to neutron-deficient Ni-58 projectile fragments at the HIRFL-CSR facility in Lanzhou, China. Masses of a series of short-lived T-z = -3/2 nuclides including Ti-41, Cr-45, Fe-49, and Ni-53 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 f p-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.
