IONIZATION OF ATOMIC-HYDROGEN UNDER HEAVY-PARTICLE IMPACT

Ionisation of hydrogen atoms in ground and metastable 2s states by imp act of protons and antiprotons has been studied at collision energies varying from 10 to 1566 keV/amu. Total and double differential cross s ections are calculated employing a final continuum state wave function which incorporates distortion due to the Coulomb fields of both the p rojectile and the target nuclei The present calculated results are com pared with the existing experimental findings as well as other theoret ical predictions.
