We study bottomonium production in association with an η meson in e+e− annihilations near the Υ(5S), at a center of mass energy of s√=10.866GeV. The results are based on the 121.4fb−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
