Query: Discrimination of alpha and beta/gamma interactions in a TeO$_2$
  bolometer   TeO$_2$ crystals have proven to be superb bolometers for the search of
neutrinoless double beta decay in many respects. However, if used alone, they
do not exhibit any feature that allows to discriminate an alpha energy deposit
from a beta/gamma one. This fact limits their ability to reject the background
due to natural radioactivity and eventually affects the sensitivity of the
search. In this paper we show the results of a TeO$_2$ crystal where, in
coincidence with its bolometric heat signal, also the luminescence light
escaping the crystal is recorded. The results show that we are able to measure
the light produced by beta/gamma particles, which can be explained as due to
Cerenkov emission. No light is detected from alpha particles, allowing the
rejection of this background source.
