Measurement of high momentum transfer pi- p ---> pi0 n at 5.9 gev/c

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

Phys.Lett.B 51 (1974) 390-392, 1974.

Inspire Record 95079 DOI 10.17182/hepdata.27932

The differential cross section for π − p → π 0 n has been measured in the t range 1.8 ⩽ | t | ⩽ 8.2 (GeV/ c ) 2 by a counter-spark chamber experiment detecting the neutron and both π 0 decay photons. A broad minimum was found, centered at | t | = 5.2 (GeV/ c ) 2 .

Pion-deuteron scattering near the 3-3 resonance

Gabathuler, K. ; Cox, C.R. ; Domingo, J.J. ; et al.

Nucl.Phys.B 55 (1973) 397-407, 1973.

Inspire Record 84138 DOI 10.17182/hepdata.32565

The elastic scattering of positive pions by deuterium has been studied using a scintillating target to detect the recoil deuteron. In addition to the angular distribution measured for 256 MeV incident energy, the energy variation of the fixed angle cross section ( θ lab =160°) has been determined between 141 MeV and 256 MeV. The former is in qualitative agreement with a simple multiple-scattering calculation, but the energy dependence is poorly reproduced.

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.

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.
