From measurement of /eta//r arrow/2..gamma.. emitted in /ital p/bar /p/ annihilation at rest, we have derived the yield, or its upper limit, of annihilation into two mesons /ital p/bar /p//r arrow//eta//ital M/ for /ital M/=/phi/, /eta/', ..omega.., /rho//sup 0/, /eta/, and ..pi../sup 0//..gamma.. (sum of ..pi../sup 0/ and ..gamma..), the branching ratio of the inclusive /eta/ production /ital p/bar /p//r arrow//eta//ital X/ for different charge multiplicities of /ital X/, and the inclusive /eta//..pi../sup 0/ ratio. An upper limit for the inclusive /eta/' production /ital p/bar /p//r arrow//eta/'/ital X/ has also been obtained.
