We report measurements of the observed cross sections for e +e- → ωπ+π-, ωK+K-, ωpp̄, K+K -ρ0π0, K+K -ρ+π-+c.c., K*0K -π+π0+c.c., K*+K -π+π-+c.c., φπ+π -π0 and ΛΛ̄π0 at √s = 3.773 and 3.650 GeV. Upper limits (90% C.L.) are given for observed cross sections and for ψ(3770) decay branching fractions for production of these final states. These measurements are made by analyzing the data sets of 17.3 pb-1 collected at √s = 3.773 GeV and 6.5 pb-1 collected at √s = 3.650 GeV with the BES-II detector at the BEP...
