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.
