A Proposed Source of Atomic Hydrogen Suitable for the Measurement of Total and Partial Scattering Cross Sections

Abstract

Whilst extensive theoretical work on e+ - H scattering has been reported1,2, there have been no experimental measurements on this system since it is difficult to produce atomic hydrogen in large quantities in a form suitable for scattering applications. With the advent of intense e+ beams it is feasible to perform experiments using sources of H which have been applied to the scattering of electrons and protons3. Measurements of various differential scattering and total ionisation cross sections are planned at the Brookhaven beam4. In this contribution we wish to draw attention to another type of H source which may produce area densities ≃ 1015 atoms cm−2 such that many cross sections can be measured using moderate intensity e+ beams.KeywordsTotal Cross SectionProton BeamEnergy ShiftScatter Cross SectionFlight PathThese keywords were added by machine and not by the authors.
