The acoustic collapse effect on the structure of collisionless weak shock waves propagating at an angle to magnetic field in the low pressure plasma is considered. In terms of the three-dimensional Kadomtsev-Petviashvili equation, it is determined that an acoustic wave collapse appears under definite conditions in media with positive dispersion. The influence of small amplitude wave radiation on this process is investigated. It is shown that in connection with weak oblique shocks, the collapse of a fast magnetic sound represents a new dissipation mechanism providing energy transfer to ions. Estimates of collisionless shock wave width and effective frequency of energy transfer to ions stipulated by the collapse are given. Comparison with other three-wave nonlinear processes is carried out. It is demonstrated that they are stongly supressed due to exciting of oscillations from the shock wave front.
