“…The two-body interaction is PEST3 (1S0)+ PEST4 (3S1-3D1) and Doleschall's rank-1 potential for P-and D-waves [-8, 16, 18] and includes the approximate Coulomb correction introduced by Doleschall [19]. The dashed lines represent the same calculation, but without Coulomb correction [8].…”

“…Obviously, reliable approximation schemes are necessary to calculate Coulomb effects "practically", when realistic force models are employed for the strong interaction. The Coulomb correction used here was introduced by Doleschall [19]. The real amplitude ofp-d elastic scattering could be expressed as a sum of the Rutherford amplitude and the Coulomb distorted nuclear amplitude (T~N).…”

Measurement of $$D(\vec p,p)D$$ elastic scattering at 10.0, 12.0, 14.1 and 16.5 MeV especially for small forward and extreme backward scattering angles

Abstract. The D(ff, p)D elastic scattering was investigated especially in theCoulomb sensitive scattering regions. Angular distributions of the differential cross section and of the analyzing power Ay, with emphasis on small scattering angles, were measured at 10.0 and 14.1 MeV. For extreme backward angles up to ~.m. = 179~ the differential cross section was measured at 12o0, 14.1 and 16.5 MeV. The data have been compared with recent Faddeev calculations based on the realistic meson-exchange Paris potential and including an approximate Coulomb correction. There are discrepancies between the data and the calculations especially for the analyzing power. This indicates that the approximate treatment of Coulomb effects and possibly also the purely rmclear part of the calculations need to be improved.

“…For the latter assumption, an ad ho@ approximation for the long-raage Coulomb parts was given by Doleschall et nl. , [30,31], although geauine n-d scattering amplitude was used in their method. In the preseat work we adopted the Doleschall approximation for simplicity (see Fig.…”

The effects of the three-body force are investigated in the three-nucleon systems. The threebody Faddeev equation is completely solved with a phenomenological three-body force which can reproduce the triton binding energy. The adopted two-body force is the PEST potential (or the Ernst-Shakin-Thaler's separable expansion of the Paris potential) up to J = 2. Calculated results of the differential cross section, and the values of the doublet and the quartet n-d scattering lengths, agree very well with the experimental data. The calculated three-body-force effects on the N-d scattering observables A", iTqq, T20, TqI, Tqq are also discussed together with the Doleschall-type Coulomb correction.PACS number(s): 21.30. +y, 21.45.+v, 25.10.+sThe necessity of the three-body force has been claimed by a number of investigations. Phillips observed a strong correlation among the theoretically calculated n-d spindoublet scattering length sa"d and the triton binding energy [1]. Slaus et aL claimed that the three-body force is necessary to obtain consistent values of the a""scattering length from the reactions 2H(n, p)nn and H(p, s )nn [2,3]. It was also mentioned that the discrepancy between the experimental and the theoretical triton binding energies and other observables which are related to the triton wave function can be removed by the three-

“…The loci for values of a between 122 and 139' were too sma11 to resolve as a ring; the SCRE point was assumed [19]. Another separable potential was generated by Heidenbauer and Plessas [20] in which greater care was taken with the form of the off-shell amplitudes.…”

Measurements of the unpolarized triple differential cross section and the A~t ensor analyzing power for the 'H(d, pp )n reaction were made using a 94.5 MeV polarized deuteron beam at the Indiana University Cyclotron Facility. Scattering angles i6 and P) and energy information were recorded for the two emerging protons using large-area wire chambers backed by stopping plastic scintillator detectors. Events were selected that were close to the symmetric constant relative energy geometry in order to enhance the sensitivity of the observables to off-shell and three-body effects. The measurements covered values of a, the center-of-mass angle between the incoming proton and the outgoing neutron, from 72 to 180'. Comparisons are made to Faddeev calculations that use either separable potentials or an exact treatment of the S-wave nucleon-nucleon interaction in conjunction with a perturbative treatment of higher partial waves. While none of these calculations, which use only two-nucleon interactions, is completely satisfactory, there remains too much variation among different theoretical treatments to demonstrate the need for including additional dynamical features in the three-body model.
