[Nuclear Physics] photoelectric peak

[CarmenGonzalez]

Homework Statement

The material of which a gaseous detector is constituted has the following values of mass attenuation coefficients for a given photon energy:

Rayleigh: 0.0084 cm² / g

Photoelectric: 0.071 cm² / g

Compton: 0.022 cm ² / g

Calculate the relative intensity of the photoelectric peak (i.e. the ratio of the peak integral to the integral of the whole spectrum), assuming that only this effect contributes to the events recorded at the peak.
