High-lying P-wave resonances in PS-H scattering below the p+Ps$^-$ threshold

POSTER

Abstract

Here, we present a calculation of P-wave resonances lying below the p + Ps$^-$ threshold by using the method of complex- coordinate rotation [1]. The present work is a continuation of our recent investigation of high-lying S-wave resonances in Ps- H scattering below the same p+Ps$^-$ threshold [2]. Using elaborate Hylleraas wave functions in which all the six inter- particle coordinates are included [3], resonance energies and widths for several lower members of a Rydberg series are calculated. At the meeting, we will compare our results with those of an earlier calculation [4].\\[4pt] [1] Y. K. Ho, Phys. Rept. 99, 1 (1983), and references therein.\\[0pt] [2] Z.-C. Yan and Y. K. Ho, Phys.
