Determination of antiproton-neutron amplitude from elastic�p-deuteron scattering at 600 MeV/c

Abstract

The elementary p-neutron amplitude has been obtained from Glauber's model analysis of p-d elastic scattering data at 600 MeV/c, taking into account the D-state component of the deuteron. The results are compared with the p-nucleus analysis and the .~N potential model predictions.

“…As was shown in detail in Refs. [23,[40][41][42][43][44][45], in forward elastic scattering of antiprotons off nuclei the Glauber theory, though in principle a high-energy approach, works rather well even at fairly low antiproton beam energies like 50 MeV. This has to be compared with proton-nucleus scattering where the Glauber theory is known to give reliable results only for energies in the order of 1 GeV or above.…”

“…That allows one to express the scattering cross section via fp N (q), S(q) and the deuteron wave function. Since the D-wave component of the deuteron wave function becomes important only in the region of the first diffraction minimum of the differentialpd cross section [23], we neglect its contribution in the present calculations and take into account only the S-wave component. As seen from Eq.…”

“…Where it can not lead to misunderstanding, we will also use literal notations τ = p, n. 2 See, for example, ref [9]. where α of the pn amplitude was extracted from pd elastic scattering.…”

“…In order to produce an intense beam of polarized antiprotons, the collaboration is going to use antiproton elastic scattering off a polarized hydrogen target ( 1 H) in a storage ring [2]. The basic idea is connected to the result of the FILTEX experiment [3], where a sizeable effect of polarization buildup was achieved in a storage ring by scattering of unpolarized protons off a polarized hydrogen atoms at low beam energies of 23 MeV.…”
