Inclusive measurements of pionic double charge exchange on ~3He at low energies

摘要

Using the CHAOS spectrometer at TRIUMF pion momentum spectra and angular distributions were measured for the ~3He(#pi#~-,#pi#~+) reaction at incident energies from 65 to 120 MeV and total cross sections were deduced. The data are compared to Monte Carlo simulations for the conventional reaction process as well as to predictions for the production of the hypothetical #pi#NN resonance d' with and without collision damping.
