Multinucleon pion absorption in theHe4(π+,ppp)nreaction

Publikováno v: Physical Review C. 43:1553-1571

Three-proton emission cross sections for the $^{4}\mathrm{He}$(${\mathrm{\ensuremath{\pi}}}^{+}$,ppp)n reaction were measured at an incident pion kinetic energy of ${\mathit{T}}_{\mathrm{\ensuremath{\pi}}}^{+}$=165 MeV over a wide angular range in a

Role of the πNP11interaction in πdelastic scattering at 50 MeV

Publikováno v: Physical Review Letters. 65:1987-1990

Measurements of the vector analyzing power {ital iT}{sub 11} in {pi}{sup +}{ital d} elastic scattering at 50 MeV have been made at pion laboratory scattering angles between 60{degree} and 130{degree} using a dynamically polarized target and a magneti

Total cross sections for the A (pi+, pi+pi-) reaction at Tpi+=280 MeV

Autor: BONUTTI, FAUSTINO, CAMERINI, Paolo, RUI, RINALDO, N. Grion, D. Vetterli, F. M. Rozon

The (π+,π+π-) reaction on 2H, 4He, 16O, and 208Pb has been measured in the reaction plane at Tπ+=280 MeV and the cross sections determined. The out of plane behavior of the reaction has been accounted for by phase space and, by integration over i

Pion induced pion production on deuterium: A Quasifree process

Autor: Rinaldo Rui, M. Pavan, G. Sheffer, R.R. Johnson, G. R. Smith, N. Grion, P. Weber, M.J. Vicente-Vacas, Paolo Camerini, N.R. Stevenson, D. Vetterli, Vesna Sossi, F. M. Rozon, M. E. Sevior, G. Jones, M.J. Iqbal

A detailed experimental analysis of the π+d → π+π−pp in-plane coincidence data first presented by Rui et al. is compared to an expanded version of the Oset and Vicente-Vacas model for pion-induced pion production on a free nucleon. This extend

pi+ pi- coincidence measurement in the pi+ d ---> pi+ pi- p p reaction at T(pi+) = 280-MeV

Autor: RUI, RINALDO, CAMERINI, Paolo, N. Grion, R. R. Johnson, M. Pavan, F. M. Rozon, V. Sossi, D. Ottewell, G. Sheffer, G. Smith, N. R. Stevenson, M. J. Vicente Vacas

The pion induced pion production (π, 2π) reaction on deuterium has been studied at an incident pion energy of 280 MeV. The outgoing pions were detected in coincidence and the measured four-fold cross sections were compared with a πN → ππ N mic

Direct measurement of the tensor polarization of a polarized deuteron target

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 254:263-269

The tensor alignment p zz of a polarized deuteron target was measured directly for the first time. The measurement utilizes the tensor analyzing power T 20 of the πd to 2p reaction at 90° (c.m.), which is well determined from partial wave analysis
