γ is taken as the y intercept on the graph. Then rearrange the electronic contribution formula for EF.

Ah I see. Thank you

strong force? Its a much stronger reaction.

Homework Statement :[/B] For the decay of the ∆+ → n + π+, sketch an appropriate quark-level Feynman diagram. State which interaction is responsible for this decay. 3. The Attempt at a Solution This is more of a question to see if I'm doing it right more than anything. The first Feynman...

Doing a bit of revision at the moment and I've been looking at the baryon spin-1/2 octet and the spin 3/2 decuplet. I've noticed that a lot of particles have the same quark composition. For instance the Δ0 particle from the 3/2 ducuplet has the same quark composition as a proton. Now I know that...

Thanks Noctisdark, think i was just doubting myself but have found that it follows on from there quite nicely. Seems like an easy 5 marks on a paper!

Homework Statement f'(p) is the Fourier transform of f(x). Show that the Fourier transform of e^(ip0x)f(x) is f'(p - p0). (using f'(p) for transform) Homework Equations f(x) = 1/√(2pi) ∫e^(ipx) f'(p) dp (intergral from -∞ to ∞) f'(p) = 1/√(2pi) ∫e^(-ipx) f(x) dx (also from -∞ to ∞) The...

thanks vela, I just managed to do it with your advice.

Homework Statement Rewrite the state |ψ⟩ = √(1/2)(|0> + |1>) in the new basis. |3⟩ = √(1/3)|0⟩ + √(2/3)|1⟩ |4⟩ = √(2/3)|0⟩ − √(1/3)|1⟩ You may assume that |0⟩ and |1⟩ are orthonormal. Homework Equations The Attempt at a Solution [/B] I have a similar example in my notes however there...

Thank you mfb, think I am there now.

Forgot to say, I now see that kaon pair production must be a product of the strong force. Just trying to understand how and when I need to worry about the isospin. Or can there be two types of interaction happening simultaneously?

Thanks for your reply mfb, Think this is where i was getting confused. If the collision is: P + P → K+ + K- + P + P Then the conservation laws for the isospin aren't conserved? Following the order of the collision above the isospin would be: 1/2 + 1/2 → 1/2 + 1/2 + 1/2 + 1/2, 1 ≠ 2...

Homework Statement Question: Figure 1: QUESTION ABOVE. Homework Equations The Attempt at a Solution :[/B] P + P → K+ + K- + P + P Firstly, I just wanted to check that this is correct. I found the answer pretty quickly by googling it but have since spent a long while trying to understand...

Homework Statement QUESTION ADDED AS ATTACHMENT AS NEED TO SEE GRAPH. Homework Equations C = (12NkBπ4/5)(T/θD)3 for T<<θD C = 3NkB for T>>θD The Attempt at a Solution a.)[/B] So I assume the expression for the specific heat as a function of temperature that the question must want: C =...

First off sorry for the badly worded title. 1. Homework Statement Beginning of Question: Consider a single quantum particle of mass M trapped in the infinite square well potential, V(x), given by V(x)= 0 if 0 < x < L infinity otherwise The wave function for a particle in the n-th...
