The Fano factor and W value in xenon have been measured with a gridded ionization chamber for 5.3-MeV {α} particles. We obtained a value for the Fano factor of 0.29±{}0.02 and the W value of 21.9±{}0.3 eV. This W value is nearly equal to those for {α} and {β} particles measured by Jesse and Sadauskis [Phys. Rev. 90, 1120 (1953); 97, 1668 (1955)]. The Fano factor is considerably larger than the value reported for x rays using a proportional scintillation counter. The reason for this difference is discussed.
