Precision pion-proton elastic differential cross sections at energies spanning the Δ resonance
Precision pion-proton elastic differential cross sections at energies spanning the Δ resonance
A precision measurement of absolute pi+p and pi-p elastic differential cross sections at incident pion laboratory kinetic energies from T_pi= 141.15 to 267.3 MeV is described. Data were obtained detecting the scattered pion and recoil proton in coincidence at 12 laboratory pion angles from 55 to 155 degrees for pi+p, …
