A comparison of pi+ and pi- total cross-sections of light nuclei near the 3-3 resonance

Wilkin, Colin ; Cox, C.R. ; Domingo, J.J. ; et al.

Nucl.Phys.B 62 (1973) 61-85, 1973.

Inspire Record 83895 DOI 10.17182/hepdata.32488

The total cross sections of 4 He, 6 Li, 7 Li, 9 Be, 12 C and 32 S for positive and negative pions have been measured in the energy range 80 to 260 MeV in a transmission experiment. Coulomb corrections were applied using real parts of the forward nuclear amplitudes as determined from dispersion relations. At the lower energies there remain large residual differences between the π + and π − scattering on the isoscalar nuclei. These can be largely understood in terms of the Coulomb distortion.

Coincidence measurements of single pi+ electroproduction

Brown, C.N. ; Canizares, C.R. ; Cooper, W.E. ; et al.

Phys.Rev.Lett. 26 (1971) 987-991, 1971.

Inspire Record 69020 DOI 10.17182/hepdata.21506

We have studied the reaction e−+p→e−+π++n by detecting the final electron and pion in coincidence. Data are presented in the region of virtual photon mass squared from -0.18 to -1.2 GeV2, and virtual photoproduction center-of-mass energy and angle from 1.85 to 2.50 GeV and 0 to 20°, respectively.

Measurement of the reaction pi- p ---> pi0 n at large momentum transfers

Brockett, W.S. ; Corlew, G.T. ; Frisken, William R. ; et al.

Phys.Rev.Lett. 26 (1971) 527-530, 1971.

Inspire Record 69039 DOI 10.17182/hepdata.21508

We present results of an experiment to measure the differential cross section of the reaction π−p→π0n between the forward and backward peaks. The measurements were made at incident π− momenta of 3.67 and 4.83 GeVc. The t range 1.7<~|t|<~4.9 (GeVc)2 was covered at the lower momentum and 1.8<~|t|<~7 (GeVc)2 at the higher momentum. At the lower momentum the cross section is essentially constant between |t|=2.4 and 4.8 (GeVc)2 while at the higher momentum the angular distribution exhibits a broad minimum centered at |t|=4.4 (GeVc)2.

$\pi^{0}$ PHOTOPRODUCTION FROM THE DEUTERON AT FORWARD ANGLES IN THE ENERGY RANGE FROM 900-MeV TO 1400-MeV

Clinesmith, Carl R. ; Tollestrup, Alvin V. ; Walker, Robert Lee ;

RX-184, 1967.

Inspire Record 51564 DOI 10.17182/hepdata.37172

The cross section for the reaction [...] was measured at the Caltech synchrotron. The [...] was detected by measuring its decay gamma rays with two lead glass, total absorption Cherenkov counters. The results are three angular distributions at k = 911, 1180, and 1390 MeV, at forward angles from 3 degrees to 90 degrees. The deuteron/proton ratio differs significantly from 2.0, but final state effects from the use of a deuteron target make impossible quantitative conclusions about the neutron cross section.
