  The low lying states in $^8$Be are believed to have a two-alpha cluster
structure and hence a large intrinsic quadrupole deformation. An earlier
calculation showed a large collective enhancement in gamma transition
probability between the low lying states leading to a 4$^+$ to 2$^+$ gamma
branch of $\sim10^{-7}$ and a resonant radiative cross section of 134 nb for
the $\alpha+\alpha$ entrance channel. We report here the first experimental
evidence for this transition through a $\gamma-\alpha-\alpha$ coincidence
measurement in the reaction $^4$He($\alpha,\alpha \gamma$)$^4$He using a gas
target. The measured cross sections on and off the 4$^+$ resonance are 165
$\pm$ 41 (stat) $\pm$35 (sys) nb and 39 $\pm$ 25 (stat) $\pm$7 (sys) nb,
respectively.
