Double electron capture cross-sections of the ground state in the collisions of He\(^\mathsf{2 + }\) and Li\(^\mathsf{3 + }\) with He

  • M. PurkaitEmail author


We investigate the problem of the double charge transfer cross-section of a helium atom by bare ions of helium and lithium at energies ranging from 60 to 200 keV/amu. The boundary corrected continuum intermediate state approximation (BCCIS) is used to calculate the capture cross-section in the ground state. The continuum state of each electron has been accounted for in the formalism. The present results are compared with existing theoretical and experimental results.
