Computation of the Attenuation of a Monoenergetic PA 2780
Electron Bundle in a-Substanoo Layero
The best agreement with experimontalresults is obtained by a
modification of the constant of 1,265 to 1924 in the formula
found by, Kazand Penfold (see table). This approximation method
Was developed with a view of ,correcting the computed ourvest'
in the first part bytaking account of the theory of a single
scatteringp in the~second part by taking account of the repeated

Computation of the Attenuation of a Monoenergetic Electron PA 2780
Bundle in a Substance Layer.
This formula aneutirs the questiones
1) In what way is:the.zonoenergetic parallel electron bundle
attenuated in dependence on the thickness of the matter?
2) In what way does the intensity of the bundle at a certain
layer of matter change on the-occasion~of a modification
of the energy of the electrons? The computed values agree
with experimentally values found by SEELIGER for aluminum,
silver and lead.
In the case.of the correction of P"(E the formula.00)

flection of monoenergetic rays of the substance layer.
