About a plasma model of positron spur in a substance

Summary form only given, as follows. As is known, wide application in physics and chemistry of a positron and positronium atom (Ps) has received a spur model formation of Ps atom. In the present work the new plasma submissions about positron spur, originating during passing of positrons through substance are offered. The evaluations of such characteristic parameters of positron spur, as it life-time and sizes are obtained. The kinetics of elementary processes in volume of spur is discussed also.
