Unformatted text preview: g + 1 n e g e h 3 (2 m e kT e ) 3 / 2 exp E pi kT e Because the number of particles on the lefthand side and righthand side of the equation is different, a factor g/V e remains. This factor causes the Sahajump . From microscopic reversibility one can derive that for the rate coefcients K ( p, q, T ) := v pq holds: K ( q, p, T ) = g p g q K ( p, q, T ) exp E pq kT 11.5 Inelastic collisions 11.5.1 Types of collisions The kinetic energy can be split in a part of and a part in the centre of mass system. The energy in the centre of mass system is available for reactions. This energy is given by E = m 1 m 2 ( v 1v 2 ) 2 2( m 1 + m 2 ) Some types of inelastic collisions important for plasma physics are: 1. Excitation: A p + e A q + e2. Decay: A q A p + hf...
