Pi-minus p elastic scattering at 2.51, 2.76, and 3.01 gev/c near t approximately equals -3 (gev/c)-squared

Fellinger, M. ; Gutman, E. ; Lamb, R.C. ; et al.
Phys.Rev.Lett. 23 (1969) 600-602, 1969.
Inspire Record 58788 DOI 10.17182/hepdata.21636

Differential cross sections for the elastic scattering of negative pions from hydrogen have been measured over a limited range of squared four-momentum transfer (t) in the vicinity of t≃−3 (GeV/c)2 for incident pion momenta of 2.51, 2.76, and 3.01 GeV/c. These measurements confirm the existence of a minimum in the differential cross section in this region of incident momentum and scattering angle. The minimum occurs at a smaller value of t [t≃−2.6 (GeV/c)2] than has been observed at higher momenta.

Elastic scattering of negative pions from deuterons at 2.01, 3.77, and 5.53 gev/c

Fellinger, M. ; Gutman, E. ; Lamb, R.C. ; et al.
Phys.Rev.Lett. 22 (1969) 1265-1269, 1969.
Inspire Record 56484 DOI 10.17182/hepdata.21699

The differential cross sections for the elastic scattering of negative pions by deuterons have been measured for 2.01-, 3.77-, and 5.53-GeV/c incident pion momenta, over an interval of the squared four-momentum transfer from -0.25 (GeV/c)2 to ∼-1.0 (GeV/c)2. The results are consistent with calculations based on a Glauber model of the scattering process.

NEUTRON - PROTON ELASTIC SCATTERING 8-GeV/c TO 30-GeV/c

Phys.Rev.Lett. 24 (1970) 22-24, 1970.
Inspire Record 52711 DOI 10.17182/hepdata.21622

The differential cross section for neutron-proton elastic scattering was measured in the diffraction region with incident-neutron momenta between 8 and 30 GeV/c. The experiment was a spark-chamber-counter experiment, conducted at the alternating-gradient synchrotron. Results are presented and compared with currently available lower energy np data and comparable energy pp data.

Backward Photoproduction of pi0 in the Region of the P-33 Pion-Nucleon Resonance

Croissiaux, M. ; Dally, E.B. ; Morand, R. ; et al.
Phys.Rev. 164 (1967) 1623-1634, 1967.
Inspire Record 52290 DOI 10.17182/hepdata.26529

The π0 photoproduction cross section has been measured at 180° for photon energies from 220 to 380 MeV, in steps of 20 MeV, by detecting the recoil proton at 0°. The statistical accuracy of the measurements varies between 3 and 7%, depending on the energy. Absolute cross sections have been deduced from a comparison of the measurements with electron-proton scattering. The experimental data are compared with theoretical results calculated from fixed-momentum-transfer dispersion relations. Special attention is paid to the prediction of the multipoles at the first resonance, namely, E1+32, M1+32, and E0+π0 to obtain agreement with experiment.

Photoproduction of Neutral Pions for Incident Photon Energies 400-800 MeV. Search for a Resonant P-11 State and Remarks on the eta Cusp Effect

Bacci, C. ; Penso, G. ; Salvini, G. ; et al.
Phys.Rev. 159 (1967) 1124-1137, 1967.
Inspire Record 944952 DOI 10.17182/hepdata.37216

Cross sections for the photoproduction of neutral pions have been measured at the 1.1-GeV Frascati electron synchrotron for bombarding photon energies k between 400 and 800 MeV and for π0 c.m. angles of θπ*=90∘, 120∘, and 135∘. The main feature of the experiment is good resolution in incident photon energy. The results are in good agreement with the existing theories in the energy range of 450 to 550 MeV. The cross sections exhibit a smooth behavior as a function of energy for k=400−600 MeV. No immediate evidence is found of a contribution of the P11 resonance. An anomaly at the limit of statistical significance appears for k≃700−740 MeV, indicating a possible structure of the so-called second resonance. We attempt to interpret the observed anomaly as a reflection of the sharp opening of the η production channel (η cusp effect).
