Two-body exit channels in p-bar-p and p-bar-nucleus annihilations

Our previous model is used and improved to estimate branching ratios for B = 0 (N-barN) and B = 1 (N-barNN) annihilations. Particular emphasis is put on the two-body exit channels. It is pointed out that relative values of two-body exit channel branching ratios in B = 1 annihilations are largely model independent. Nuclear effects in p-bar-nucleus annihilation at rest are estimated.
