Abstract. We study the energy fluctuations of a spatially homogeneous SU(2) Yang--Mills--Higgs system. In particular, we analyze the nearest--neighbour spacing distribution which shows a Wigner--Poisson transition by increasing the value of the Higgs field in the vacuum. This transition is a clear quantum signature of the classical chaos--order transition of the system. (2 figures available upon request, accepted for publication in Modern Physics Letters A).
