Abstract

Two-color two-step resonance ionization spectroscopy of neodymium (Nd) was performed to identify more than 120 even-parity autoionizing levels and their candidate J-values. The analysis of the observed autoionizing Rydberg series yielded a value of 44,560.11 (43)_stat (2)_sys cm⁻¹ as a more accurate ionization potential of Nd. The saturation method was used to measure the transition cross-sections for some intense ionization transitions. From the measured cross-sections, the ionization efficiencies of some two-step ionization schemes were evaluated using the scheme cross-section formula to obtain several promising schemes.

利用钕的共振电离光谱确定高效的两步电离方案

对钕（Nd）进行了双色双步共振电离光谱分析，以确定 120 多个偶极自电离水平及其候选 J 值。通过对观测到的自电离里德堡系列进行分析，得出了 44,560.11 (43)stat (2)sys cm-1 的值，作为更准确的钕电离势。饱和法用于测量一些强电离转变的转变截面。根据测得的横截面，利用方案横截面公式评估了一些两步电离方案的电离效率，得出了几种可行的方案。
