The nuclear structure of ¹²⁴Xe has been investigated via measurements of the β⁺/EC decay of ¹²⁴Cs with the 8π γ-ray spectrometer at the TRIUMF-ISAC facility. The data collected have enabled branching ratio measurements of weak, low-energy transitions from highly excited states, and the 2⁺ → 0⁺ in-band transitions have been observed. Combining these results with those from a previous Coulomb excitation study, $$B(E2; 2^+_3 → 0^+_2)$$ = 78(13) W.u. and $$B(E2; 2^+_4 → 0^+_3)$$ = 53(12) W.u. were determined. The $$0^+_3$$ state, in particular, is interpreted as the main fragment of the proton-pairing vibrational band identified in a previous ¹²²Te(³He,n)¹²⁴Xe measurement, and has quadrupole collectivity equal to, within uncertainty, that of the ground-state band.
