AT.effective.Z.from.composition: AT.effective.Z.from.composition

In libamtrack: Computational Routines for Proton and Ion Radiotherapy

Description

Computes the effective atomic number for a given material composition

Usage

AT.effective.Z.from.composition(Z, weight.fraction,
 electron.densities.cm3, exponent)

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
