Query: The limits of volume reflection in bent crystals   We show that theory predictions for volume reflection in bent crystals agree
with recent experimental data. This makes possible to predict volume reflection
angle and efficiency in a broad range of energy for various crystals. A simple
formula is proposed for volume reflection efficiency. We derive the physical
limits for application of crystal reflection at high-energy accelerators where
it may help beam collimation.
