Pasyuk, E.A. ; Alexakhin, V.Yu. ; Gogolev, S.I. ; et al.

Phys.Rev.C 55 (1997) 1026-1032, 1997.

Inspire Record 425528 DOI 10.17182/hepdata.25740

A study of the reaction pi+ + d --> p + p has been performed in the energy range of 18 - 44 MeV. Total cross sections and differential cross sections at six angles have been measured at 15 energies with an energy increment of 1 - 2 MeV. This is the most systematic data set in this energy range. No structure in the energy dependence of the cross section has been observed within the accuracy of this experiment.

Precise pion electroproduction in the p (e, e-prime pi+) n reaction at W = 1125-MeV

Blomqvist, K.I. ; Boeglin, W.U. ; Böhm, R. ; et al.

Z.Phys.A 353 (1996) 415-421, 1996.

Inspire Record 428951 DOI 10.17182/hepdata.16502

The reactione+p →> e+π++n at c.m. energyW=1125MeV and momentum transfer Q2=0.117GeV2/c2 has been measured. The transverse and longitudinal structure functions have been separated by varying the polarization of the virtual photon (Rosenbluth plot) with a 3 to 4% error. In addition the longitudinal-transverse interference term has been determined measuring the right-left asymmetry with an accuracy of 3%. The experimental data are compared to model calculations, and the sensitivity of the results to the axial and pion formfactors is discussed.

BACKWARD PION - DEUTERON ELASTIC SCATTERING FROM 1.75-GeV/c TO 3.1-GeV/c

Abramov, B.M. ; Ayrapetov, E.A. ; Bagdasaryan, L.S. ; et al.

Phys.Lett.B 189 (1987) 295-298, 1987.

Inspire Record 219757 DOI 10.17182/hepdata.40130

Measurements of the differential cross section for π − d elastic scattering in the backward angular region (−1 ⩽ cos θ cms ⩽ −0.98) are presented. These measurements were made at nine incident pion momenta P π ranging from 1.75 to 3.09 GeV/ c and at the largest values of q 2 [up to 7 (GeV/ c ) 2 ] ever reached experimentally; here q 2 is the momentum transfer squared. The differential cross section was found to decrease rapidly with increasing momentum d σ d Ω cms (180°) ∼ P −15.7 π , d σ d t ∼ (q 2 ) −12.8 . The data are compared with predictions of Regge and quark bag models.

Energy Dependence of Backward $\pi^- D$ Elastic Scattering in the 1-{GeV} - 2-{GeV} Region

Abramov, B.M. ; Dukhovskoi, I.A. ; Kishkurno, V.V. ; et al.

Nucl.Phys.A 372 (1981) 301-316, 1981.

Inspire Record 172727 DOI 10.17182/hepdata.37082

Differential cross sections for backward π − d elastic scattering (−1 ≦ cos θ c.m ≦ −0.98) have been measured at fourteen momenta from 0.98 to 1.76 GeV/ c and at 2.45 GeV/ c . Energy dependence of the cross section exibits a new wide structure at √ s ≈ 2.9 GeV. Possible mechanisms of the reaction accounting for this structure are presented. Experimental data are compared with theoretical calculations.

π+ meson production in low-energy proton collisions with carbon and copper nuclei

Akimov, Yu.K. ; Gajsak, I.I. ; Guber, F.F. ; et al.

JINR-1-80-294, 1980.

Inspire Record 1395696 DOI 10.17182/hepdata.39684

Differential and double differential cross sections of positive pion production by 240 MeV protons on carbon and copper nuclei are measured. The energy dependence of differential cross section for copper nucleus at 90 deg angle within the 240-500 MeV energy range of protons and angular dependence of the integrated differential cross section are obtained. It is shown that the differential cross section at 250 MeV is 80 times less than that at 585 MeV
