/sup 1/P/sup o/ resonances of helium below the n = 4 threshold of He/sup +/

Journal Article · · Phys. Rev. A; (United States)
In this work the lowest eleven /sup 1/P/sup o/ resonances of helium below the n = 4 threshold of He/sup +/ have been investigated. The QHQ eigenvalues of these states have been calculated and found to be lower than the QHQ results of Oberoi and of Herrick and Sinanoglu. The saddle-point energies of these resonances are found to be generally in good agreement with the experimental results of Madden and Codling and of Woodruff and Samson. The oscillator strengths from both the 1/sup 1/S/sup e/ and 2/sup 1/S/sup e/ states to these autoionizing levels are also calculated together with various pertinent expectation values which allow us to arrange the eleven states into six Rydberg series, one of which we identify as the resonant series seen in the experiments.
