摘要：

Two-parameter sets of solutions to the classical field equations in the massless phi4 model and SU(2) gauge theory are found, each solution presumably describing a multi-particle instanton-like transition at high energy. In the limit of a small number of initial particles, the probability of the transition is suppressed by exp(- 2S0), where S0 is the instanton action.
