Ps formation calculation scheme inside muffin-tins

Calculation scheme of positronium (Ps) formation inside muffin‐tins is presented for calculation program code of angle‐resolved Positronium formation spectroscopy(ARPsFS) Layered KKR method is used in this calculation Spectrum calculation of angle-resolved Ps formation will be performed for a lot of conditions by building in the new program code into the previous calculation where Ps formation is calculated only around surface barrier outside of the topmost muffin‐tin Subroutines for the present calculation are supplied in the angle- resolved photoemission spectrum calculation code, SLON established by Blake, Koukal and Larsson
