Radiative lifetime of O2+

Abstract

The radiative lifetimes of ν′=1, 2, and 3 levels of the b⁴Σ state of ${\mathrm{O}}_2^{+}$ have been measured by a delayed coincidence method using an electron beam as excitation source. The data showed no clear variation from band to band and an average lifetime was found to be 1.05 ± 0.15 × 10⁻⁶ sec.
