Query: Radiative decays in bottomonium beyond the long wave length
  approximation   We revisit the nonrelativistic quark model description of electromagnetic
radiative decays in bottomonium. We show that even for the simplest
spectroscopic quark model the calculated widths can be in good agreement with
data once the experimental masses of bottomonium states and the photon energy
are properly implemented in the calculation. For transitions involving the
lower lying spectral states this implementation can be easily done via the Long
Wave Length approximation. For transitions where this approximation does not
apply we develop a new method of implementing the experimental energy
dependencies.
