Nuclear collision length
Encyclopedia
Nuclear collision length is the mean free path of a particle before undergoing a nuclear reaction
, for a given particle in a given medium. The collision length is smaller than the nuclear interaction length
because the elastic and quasi-elastic (diffractive) reactions are excluded from its definition.
Nuclear reaction
In nuclear physics and nuclear chemistry, a nuclear reaction is semantically considered to be the process in which two nuclei, or else a nucleus of an atom and a subatomic particle from outside the atom, collide to produce products different from the initial particles...

Nuclear interaction length
Nuclear interaction length is the mean path length required to reduce the numbers of relativistic charged particles by the factor 1/e, or 0.368, as they pass through matter....
