Hello everyone. I have an understanding problem with the Optical theorem definition.
From Wikipedia :
"In physics, the optical theorem is a general law of wave scattering theory, which relates the forward scattering amplitude to the total cross section of the scatterer. It is usually...
Hi everyone,
I have a problem with the following equation that is related to Cerenkov counter. You can find it at page 56 of "Introduction of High Energy Physics" by Perkins.
The equation is the following:
sin ^{2} (\theta _1)=1-\frac{1}{\beta...
Hi Born2bwire,
thanks a lot for the explanation it does clear my mind. OK, I'll try to find the solutions and see if I manage to plot them in Matlab.

Hi everybody !
Maybe this post should go under partial differential equations but I'm not sure...
I have the following problem and I would like to know if someone could give me some hints or something to read related to this.
I'm studying multiple reflections of acoustics waves in a...
Hi and thanks a lot for the answer !
There is still something I don't get .. how do you get L=0 or L=2 with S=0 and more how do you get J=1 = L+S = 1+1 ?? if L=1 and S= 1 shouldn't you get in this case 0 or 2 . (L-S or L+S)?
Isn't this correct :
|L-S|<= 1<= L+S
if S= 0 then you...
Hello all ! I was trying to solve the following problem : you have a particle with spin J=1 and unknown parity that decays into 2 indentical particles of spin = 1/2
We want to know how much the angular momentum of the final state is and also the final total spin.
Now, my reasonment was...
