Abstract: We study bottomonium production in association with an η meson in e+e- annihilations near the Υ(5S) , at a centre-of-mass energy of s=10.866  GeV. The results are based on the 121.4 fb -1 data sample collected by the Belle experiment at the asymmetric-energy KEKB collider. Only the η meson is reconstructed and the missing-mass spectrum of η candidates is investigated. We observe the e+e-→ηΥJ(1D) process and find evidence for the e+e-→ηΥ(2S) process, while no significant signals of Υ(1S) , hb(1P) , nor hb(2P) are found. Cross sections for the studied processes are reported.
