Ionization in liquid hydrocarbons: γ radiolysis yields and electron range distribution functions

Abstract
The use of an exponential distribution of initial separation distances in thermalized electron‐ion pairs in γ irradiated liquid hydrocarbons leads to the calculation of total ionization yields of Gtot = 5–6. The distribution possesses a power function tail (y−3) at large initial separations (y). The concepts of ionization and excitation in a liquid are briefly dicussed.
