Precise total cross-sections and invariant-mass distributions have been measured for photoproduction of pion pairs off the proton producing $\ensuremath p\pi^0\pi^0$ and $\ensuremath n\pi^+\pi^0$…
Measurement of the 1H(γ, p)π0 reaction using a novel nucleon spin polarimeter.
We report the first large-acceptance measurement of polarization transfer from a polarized photon beam to a recoiling nucleon. The measurement pioneers a novel polarimetry technique, which can be…
