An earlier measurement on the 4$^+$ to 2$^+$ radiative transition in $^8$Beprovided the first electromagnetic signature of its dumbbell-like shape.However, the large uncertainty in the measured cross section does not allow astringent test of nuclear structure models. The present paper reports a moreelaborate and precise measurement for this transition, via the radiativecapture in the $^4$He+$^4$He reaction, improving the accuracy by about a factorof three. The {\it ab initio} calculations of the radiative transition strengthwith improved three-nucleon forces are also presented. The experimental resultsare compared with the predictions of the alpha cluster model and {\it abinitio} calculations.
