[Auszug] The mean number of electrons, n, created by the photoelectric absorption of X rays in a gas is a function of the X-ray energy, E, and the mean energy required to create an ion pair, W, such that ? = E/W (where W 26 eV in Ar). In conventional gas proportional counters the electrons produced are ...
