Atomic ionization by electron impact: A hyperspherical approach
- Department of Applied Mathematics, University College of Science, 92 Acharya Prafulla Chandra Road, Calcutta 700009 (India)
An {ital ab initio} calculation, following a hyperspherical partial-wave method [J. N. Das, Aust. J. Phys. {bold 47}, 743 (1994)], satisfactorily represents the recent experimental triple differential cross-section results of R{umlt o}der {ital et al.} [Phys. Rev. A {bold 53}, 225 (1996)] for electron hydrogen atom ionization collisions at low energies. The qualitative agreement with their theoretical results is also good. Moreover, our results are in absolute units and in some instances our results are in better agreement with the experiments compared to their theoretical results. Here it is also exhibited that the hyperspherical partial wave method is a promising formalism for studying atomic ionization problems. {copyright} {ital 1997} {ital The American Physical Society}
