Chudakov effect for the most probable value of high-energy electron–positron pair ionization loss in thin targets

The ionization loss of a high-energy electron–positron pair in thin targets is considered. The targets not thinner than about 10 μ m are discussed. The analogue of the Landau distribution function is derived for this loss under the condition when the Chudakov effect of the pair ionization loss suppr...

Description
Summary:The ionization loss of a high-energy electron–positron pair in thin targets is considered. The targets not thinner than about 10 μ m are discussed. The analogue of the Landau distribution function is derived for this loss under the condition when the Chudakov effect of the pair ionization loss suppression is manifested. Expression for the most probable value of the pair ionization loss E MP is obtained. It is shown that the magnitude of Chudakov effect for E MP can be noticeably different from the magnitude of this effect for the restricted mean value of the pair ionization loss.
