Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Low Energy Scattering by a Compound System: Positrons on Hydrogen The formalism, developed by Kato, which gives upper and lower bounds on the phase shift for the scattering of a particle from a center of force is shown to have useful applications when the scatterer is a compound system. In particular, the problem of low energy positron scattering from, atomic hydrogen, with zero total orbital angular momentum, is studied. It is shown that at zero energy the ordinary variational calculation, which ignores second order contributions, provides a bound on the scattering length, from which a bound on the cross section is deduced. For non-zero energies a bound on the phase shift may similarly be obtained, but for a fictitious problem with cut-off potentials. If the energy is sufficiently small (less than 3 e.v., say) the error thus incurred is expected to be negligibly small. Numerical calculations performed at k = 0 and ka = 0.2 lead to the result that the effects of polarization are large enough to cause the positron to be on the whole attracted to the hydrogen atom. It is shown, independently of the Kato formalism, that in general a bound on the scattering length may be obtained from the ordinary variational calculation provided no composite bound state exists for the system.

Available in PDF, EPUB and Kindle. Book excerpt: The first conference in this series, devoted principally to the interaction of positrons in gases, was held at York University, Toronto, in July 1981 immediately preceding the XII ICPEAC in Gatlinburg, and the proceedings were published in the Canadian Journal of Physics, volume 60 (1982). So successful was this meeting that the decision was taken to hold a second one around the time of XIII ICPEAC in Berlin in 1983. London was clearly a convenient location but, rather than the obvious choice of University College London in central London, the Organising Committee decided that the beautiful and peaceful surroundings of Royal Holloway College would provide a more pleasant and intimate atmosphere for a small meeting. Even a small conference requires substantial sums of money to pay the expenses of invited speakers and when considering possible sources of funds the Organising Committee recognised that the intended format of the meeting and the international composition of the participants made it appropriate to apply to the NATO Science Committee for support under the Advanced Research Workshop Programme. This was one of the few successful applications made this year, and so it was that the conference became the 'NATO Advanced Research Workshop on Positron Scattering in Gases'. The Workshop, with approximately sixty participants, started after lunch on 19 July, 1983 and finished at mid-day on 23 July.
