AT.effective.Z.from.composition

Description

Computes the effective atomic number for a given material composition

Usage

AT.effective.Z.from.composition(Z, weight.fraction,

Arguments

Z

atomic numbers of constituents (array of size n).

weight.fraction

relative fractions of weight of constituents (array of size n).

electron.densities.cm3

if not zero, weight fractions will additionally include electron densities per volume (array of size n).

exponent

exponent for additivity rule reflecting the photon energy regime (usually 3.5 at ~ 100 kV).

Value

effective.Z

effective Z
