Some results on correlated pairs emitted after negative pion absorption at rest in 12C

In this paper, the authors present some of the experimental results achieved in a kinematically complete experiment performed at the TRIUMF cyclotron and concerning the investigation of the reactions at rest 12C(π-,nX), X being n,p. The (π-,nX) energy excitation spectra corresponding to the opening angle of 1800-1600 are shown. Moreover, the (n,n), (n,p) and (n,d) angular distributions are shown. (Auth.)
