Test of N.bar.N potential models: isospin relations in p.bar.d annihilations at rest and the search for quasinuclear bound states

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/ wher...

description 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/. The frequencies for pi /sup -/ omega and rho /sup -/ pi /sup 0/, and pi /sup -/ eta and pi /sup -/ eta ' and the corresponding frequencies for pp annihilations are used to determine isoscalar and isovector contributions to the protonium wave function. We observe rho - omega interference in pp to pi /sup +/ pi /sup -/ eta and pi /sup +/ pi /sup -/ pi /sup 0/ annihilation. The annihilation rate for pd to K/sup -/K/sup 0/p confirms the dominance of the isovector contribution to NN to KK annihilations. Furthermore, we searched for narrow quasinuclear bound states close to the NN threshold, but with negative outcome. (44 refs).
