Problem 26, GR8677

Postby ali8 » Mon Jun 27, 2011 5:00 pm

Hello,

I am referring to this problem

http://grephysics.net/ans/8677/26

I understand the solution (it's very easy) but that equation, where there's Z-B
where B is to account for the screening effect, such that B=1 for S and B=7.4 for L.

My question: Where can I find this specific piece of detail about the screening effect?

I have Serway's Modern Physics but I cannot find it anywhere there...

Thanks !

Well, read this. Especially section 1.5.

Thank you indeed.

But that equation is only a special case for transition from K to L.

I have to say that I do understand the cpncept, I just want to know

where does that equation (the general one in my link above) exist ?

I mean in which book...

BTW, what was the name of the book in your link ?
