UDC 517.9 We consider a gas each particle of which is characterized by a pair $(x,v_x),$ where $x\in \mathbb R^d$ is the position and $v_x\in \mathbb R^d_0=\mathbb R^d\setminus \{0\}$ is the velocity. Gibbs measures are defined on the cone of vector-valued measures. Our aim is to prove their existen...
