Abstract

The triple differential cross sections estimation have been ascertained theoretically for the ionization of metastable 3d-state hydrogen atoms by electron at 150 eV, 200 eV and 250 eV for assorted kinematic conditions exerting a multiplex scattering principle. The existent new-findings are assimilated with the theoretic data of hydrogenic metastable 2S, 3S and 3P states as well as the hydrogenic ground state experiment. An analysis of the attained observations reveals qualitative fitness with those of compared results specially with hydrogenic ground state BBK model, ground state experimental data and metastable state 2S state results. This is a new theoretical work on hydrogenic metastable 3d state ionization by electron. The substantial progress of the current study offers a wide scope for empirical study in ionization process.

Summary

Introduction

In high energy ion-atom collisions, ionization is one of the most momentous reactions. Electron atom ionization collision on different cross sections has become gradually interesting over the last four decades both theoretically and experimentally for non-relativistic [2]-[21] as well as relativistic [22]-[25] energies. Ionization of the hydrogenenic atom by electron is a good image for perturbation theory because of the existence of empirical consequence. In this text, the electron-electron coincidence experiments called (e, 2e) experiments which offer a translucent idea of the kinematics of the collisions by delivering knowledge about the direction of the scattered and ejected electrons. Current results are compared with previous related theories [15], [19], [20]
