Analysis of the 4f,thinsp;v=3 state of NO

摘要

The longhyphen;range force model has been used to analyze high resolution spectra of the nearly nonpenetrating 4f,v=3 state of NO. The energy levels are described to an accuracy of 0.03 cmminus;1by a fit with four adjustable parameters. The quantum defects are predicted to better than 0.1percnt;, showing that the 4fstate is almost completely unperturbed. Implications for previously reported measurements of the autoionization rates are discussed.
