| Abstract: | Schwinger variational principle has been used to calculate triple differential cross-sections for ionization of hydrogen atoms
by positrons at intermediate and high energies for Ehrhardt type asymmetric geometry. The results agree in general with the
calculations of Brauneret al 8] and with the second Born calculation. |
