Absolute photoionization cross sections

Absolute photoionization cross sections for the ions N2+, N3+, O3+, O4+, F3+ , F4+ and Ne4+ are measured using the merged-beam technique, combining the synchrotron radiation...采用合并束技术（merged-beam technique）结合同步辐射（synchrotron radiation），对N2+、N3+、O3+、O4+、F3+、F4+及Ne4+等离子的绝对光电离截面进行了测量。
