i am thinking that its something to do with this but this involves 3D stuff, so i think i need to simplify it down...yeah?

hmm i am getting confused... ok lets start from the begining.... we are given that [math] \lambda = v \rho [/math] then i think i need to somehow manipulate the equation in my first post...hmmmmm

then i get this [math] D = \sqrt{\frac{2kl}{\frac{1}{2}k(sin(2la)+la/k)+lcos^2(la)}} [/math] and [math] F = \sqrt{\frac{2kle^{2ka}cos^2(la)}{\frac{1}{2}k(sin(2la)+la/k)+lcos^2(la)}} [/math]

ok so could also use the continuity of psi at x = a [math] Fe^{-ka} = Dcos(la) [/math] ?

so can i go: [math] \int^a_0D^2cos^2(lx)dx+\int^\infty_aF^2e^{-2kx}dx=1/2 [/math] ??

oh E_G is Gamow energy

Hi all. i can't quite figure out how to modify the equation for this alpha particle decay stuff....any ideas ? i think i need to modify this equation: anyway, help would be great! thanks guys & gals Sarah

should be 1?

Hi all I was wondering how you go about normalising the even bound state wavefunction for the finite square well? eg. so i have to find F and D. this what i got so far: i can't seem to find the answer to this 'normalising' problem anywhere! any ideas guys? Thanks Sarah

dont worry bout it, i got it.

nm, i got it! yay!

nm, i got it!

anyone?

Hey everyone i have done all this problem, except the "hence" bit. i just can't quite get it... could anyone please give me a hint Thanks Sarah

should i put this thread in the "homework help" section instead?

Hi hmm...i think i have solved this problem but neither of my 2 answers look like a Laguerre polynomial..... problem: my solutions: :S Sarah

Hi all, would anyone be able to give me a bit of help with this problem: this is what i have done so far (i am now stuck ): thanks Sarah

nm, got it!

Hey all, this is just small problem on dirac notation, just want to make sure that i have some idea of what i'm doing (we only just started this stuff this week! ) heres the question: and heres my answers: -Sarah

yeah latex is defintely the way to go. If your using a mac (like me! ) use a program called "TeXShop", its free and really really good!

nm, got it. thanks once again for all your help Atheist! -sarah

yep ok i see. so its the right way to do the calulation, but i can see that it is quite a rough approximation. Thank you for your help Atheist -sarah

ok cool, thats what i was hoping for! Thank you very much Tom!
