The $\pi \pi$ interaction in nuclear matter from a study of the ${\pi }^{+}A\to {\pi }^{+}{\pi }^{\pm }{A}^{\prime }$ reactions

F. Bonutti, P. Camerini, E. Fragiacomo +2

The pion-production reactions ${\pi }^{+}A\to {\pi }^{+}{\pi }^{\pm }{A}^{\prime }$ were studied on ${}^{2}H$, ${}^{12}C$, ${}^{40}Ca$, and ${}^{208}Pb$ nuclei at an incident pion energy of $T_{{\pi }^{+}}$=283 MeV. Pions…
