We have measured the collisional self-broadening of the cesium 6S1/2→5D3/2 electric quadrupole (E2) transition at 689 nm for temperatures from 220 to 370 °C, corresponding to cesium number densities from 3×1015 to 1.5×1017 cm-3. This E2 transition may have utility for studies of atomic parity nonconservation (PNC), and the collisional self-broadening represents an important systematic effect which must be understood for an accurate measurement of PNC. We find a value for this broadening of 1.32±0.06310-8 cm3 s-1, which is consistent with what would be expected for a quadrupole-quadrupole resonance interaction. To the best of our knowledge, no quantitative measurement of the self-broadening of an atomic E2 transition has been reported previously in the literature.
