Abstract

The International Business Machines Card Programmed Calculator has been wired (by members of the NOTS Mathematics Division) to compute wave functions of several terms of the sharp and diffuse series of potassium (up to 11<i>s</i> and 9<i>d</i>). Transition probabilities and “oscillator” and “line strengths” estimated from these are reported. The computational procedure employed was that developed by Biermann and Lübeck. Perfect agreement with Biermann and Lilbeck was obtained for a check calculation of the 4<i>p</i> wave function. The reliability of the results is discussed.
