Recent high-precision mass measurements and shell model calculations~[Phys.Rev. Lett. {\bf 108}, 212501 (2012)] have challenged a longstanding explanationfor the requirement of a cubic isobaric multiplet mass equation for the lowest$A = 9$ isospin quartet. The conclusions relied upon the choice of theexcitation energy for the second $T = 3/2$ state in $^9$B, which had twoconflicting measurements prior to this work. We remeasured the energy of thestate using the $^9{\rm Be}(^3{\rm He},t)$ reaction and significantly disagreewith the most recent measurement. Our result supports the contention thatcontinuum coupling in the most proton-rich member of the quartet is not thepredominant reason for the large cubic term required for $A = 9$ nuclei.

Second T = 3/2 state in $^9$B and the isobaric multiplet mass equation
