$\bar{\rm p}{\rm p}$-annihilation into $\omega\pi^{0}$, $\omega\eta$ and $\omega\eta^{\prime}$ at 600, 1200 and 1940 MeV/$c$ / Crystal Barrel Collaboration
The annihilation channels p¯p→ωπ0,ωη,ωη′p¯p→ωπ0,ωη,ωη′ were studied with the Crystal Barrel detector at LEAR at p¯p¯-momenta of 600, 1200, and 1940 MeV/ cc. In most cases angular distributions were measured which allowed a complete JPJP-analysis using the helicity formalism. [...]

Study of $f_{0}$ decays into four neutral pions / Crystal Barrel Collaboration
A simultaneous analysis of two different 5 pi final states from pN annihilation at rest is used to study the decays of isoscalar 0/sup ++/ states into 4 pi /sup 0/. The data demand two scalar states, the f/sub 0/(1370) with m=1395+or-40 MeV/c/sup 2/, Gamma =275+or-55 MeV/c /sup 2/ and the f/sub 0/(1500) with mass and width compatible with previous findings.

Antiproton-proton annihilation at rest into $K^{+}K^{-}\pi^{0}$ / Crystal Barrel Collaboration
The annihilation channel pp to K/sup +/K/sup -/ pi /sup 0/ in liquid hydrogen at rest has been studied with the Crystal Barrel detector at LEAR. The measured branching ratio is: BR(pp to K/sup +/K/sup -/ pi /sup 0/)=(2.37+or-0.15)*10/sup -3/. [...]

Test of N.bar.N potential models : isospin relations in p.bar.d annihilations at rest and the search for quasinuclear bound states / Abele, A ; Adomeit, J ; Amsler, Claude ; Baker, C A ; Barnett, B M ; Batty, C J ; Benayoun, M ; Bischoff, S ; Blüm, H P ; Braune, K et al.
We have determined branching ratios for antiproton annihilations at rest on protons or neutrons in liquid deuterium which we compare to frequencies of isospin-related processes in antiproton-proton annihilations. Using the annihilation rates into pi /sup 0/ pi /sup 0 / and pi /sup -/ pi /sup 0/ where the annihilation took place on the proton or neutron, respectively, we discuss the fraction of S-wave and P-wave annihilation in liquid D/sub 2/.

Measurements of two-body branching ratios for pbarp annihilations at rest in liquid and gaseous (12 rho sub S sub T sub P) hydrogen are reported. Channels studied are pbarp-> pi sup 0 pi sup 0 ,pi sup 0 eta, K sup 0 sub S K sup 0 sub L , K sup + K sup -. [...]
