Homework Statement
I see graphs for the total mass attenuation coefficient such as this all over the web:http://scientificsentence.net/Radiations/images/attenuation_coefficients.jpg
However, I can't find data on the individual attenuation coefficients such as the photoelectric or Compton...
A more direct question would be how can I use the Klein-Nishina formula to determine the probability of a photon scattering at a particular angle after a Compton interaction? I would appreciate any further help
I am researching how photon intensity attenuates within matter and am a bit confused by what I have come across.
Several sources state that the attenuation of photon intensity within matter is exponential (as a function of depth). The explanation is that photon interactions with electrons in...
Thank you for your response. So if the particle must hit somewhere in this area around the scattering centre to be scattered at an angle Θ, then is the probability of the incident particle being scattered at the angle Θ directly proportional to this area? If so, would I be able to describe the...
Thank you all, I think I understand it a little better now but am still a bit unsure (i'm not very well read in particle physics or maths). What I really need to know is the significance of the numerical value produced by the Klein-Nishina formula...
In particle physics, what is a differential cross section? I think I understand what a cross section is, but I can't find any information on what a differential cross section is. I don't see how a cross section could be differentiated.
Hello,
Why does electromagnetic wave intensity attenuate exponentially with depth from its incident intensity in an object? Why is the relationship exponential? I just need a nudge in the right direction or more if you are willing. Thank you for any help!
In electron ionisation, how does the electron beam transfer energy to the molecule being ionised? Is it via the interaction of the electric fields of the electrons in the molecule and the beam? If so, what type of interaction? And why is ionisation efficiency of the beam maximised when the...
Thank you for your response. I must apologise - I've never really learned how to use calculus in this manner and still don't quite understand. If it's not too much effort, could you write out the integral? I have run out of time and don't understand how to manipulate integrals. It would be much...
I have an experiment in which I have two solenoids where one induces an EMF in the other. I then introduce copper plates between the two coils and measure the decrease in induced EMF in the second solenoid. How could I calculate the power loss due to eddy currents induced in one of the copper...

How would I calculate the magnetic flux density of the magnetic field generated by eddy currents induced in a circular plate? I decided it would be reasonable to approximate this by considering the flux density of a current loop. However, it is my understanding that eddy currents are induced...
