The ion charge state yields resulting from the photoionization of neon gas have been measured with time-of-flight ion charge state spectroscopy for excitation energies in the K-edge region. The decay of the [1s]3p resonance excited state results in the formation ion charge states Ne{sup +}, Ne{sup 2+}, Ne{sup 3+}, and Ne{sup 4+}, with a branching ratio of 0.65:0.32:0.030:0.002, whereas the final charge state for the decay of higher-order [1s]np(n{ge}4) and [1s]{var_epsilon}p continuum excitations is mostly Ne{sup 2+}. We have measured {bar q}, the mean charge from photoionization, for excited states near the K edge as a function of photon energy. Postcollision interaction effects are shown to be quite small. {copyright} {ital 1997} {ital The American Physical Society}
