Abstract. We study the spectral properties of a charged particle confined to
a two-dimensional plane and submitted to homogeneous magnetic and
electric fields and an impurity potential. We use the method
of complex translations to prove that the life-times of resonances
induced by the presence of electric field are at least Gaussian
long as the electric field tends to zero.
