I'm currently studying for an exam, where I'm looking into decays and gamma radiation. I then have a diagram where there are stuff like "Compton scattering", "Single Escape Peaks", "Double Escape Peaks" which all are calculated if I know the value of the photopeak. And all these three are actually quite well explained
But, nothing in my notes actually tells me what the photopeak is :/
So could anyone explain, just briefly, what the photopeak is/means, at least in this regard.
Thanks in advance :)
