A Q-value of -31.5762(30) MeV has been measured for the 12C (3He, 6He)9C reaction. The mass of 9C, when compared to its Coulomb analog levels in 9B, 9Be, and 9Li, confirms a significant deviation from the quadratic form of the isobaric multiplet mass equation, with a cubic coefficient of d = 5.7 ± 1.5 keV.
