  "abstract": "The possibility to observe new bottomonium states with $J^{PC}= 1^{--}$ in the region $10.7-11.1$ GeV is discussed. The analysis of the di-electron widths shows that the $(n+1)^3S_1$ and $n^3D_1$ states ($n\\geq 3$) may be mixed with a rather large mixing angle, $\\theta\\sim30^\\circ$ and this effect provides the correct values of $\\Gamma_{ee}(\\Upsilon(10580))$ and $\\Gamma_{ee}(\\Upsilon(11020))$. On the other hand, the $S-D$ mixing gives rise to an increase by two orders of magnitude of the di-electron widths of the mixed $\\tilde\\Upsilon(n^3D_1$) resonances ($n=3,4,5$), which originate from pure $D-$wave states. The value $\\Gamma_{ee}(\\tilde\\Upsilon(3D))=0.095^{+0.028}_{-0.025}$ keV is obtained, being only $\\sim 3$ times smaller than the di-electron width of $\\Upsilon(10580)$, while $\\Gamma_{ee}(\\tilde\\Upsilon(5D))\\sim 135$ eV appears to be close to $\\Gamma_{ee}(\\Upsilon(11020))$ and therefore this resonance may become manifest in the $e^+e^-$ experiments. The mass differences between $M(nD)$ and $M((n+1)S) (n=4,5)$ are shown to be rather small, $50\\pm 10$ MeV.",
