Hi
Just a quick question that I have been wondering about ... how do nucleons fill energy levels, and what is the maximum number of nucleons that can occupy each level?
The given pattern is:
1s, 1p, 1d, 2s, 1f, 2p, 1g, etc
I can see no obvious pattern here. Can anyone explain? I...
“Light is emitted with a central wavelength of 500 nm. First it is analysed with a Michelson Interferometer: starting from uniform illumination, one of the mirrors is displaced 2.5 mm until no new fringes can be distinguished. Then it is analysed with a Young´s Double Slit: it is observed that...
I have to work out which if these two beta-decay processes are energetically possible, given that the beta-decay energy of Li-11 is Q = 20 MeV. The two processes are:
(1)
〖Li〗_11→〖Be〗_9+2n
(2)
〖Li〗_11→〖He〗_3+〖He〗_8
I am supposed to use the energy conditions for beta-decay equations...
If the solution to the electric part of the spherical wave equations is:
E(r, t) = ( A/r)exp{i(k.r-ωt)
What happens when t=0 and the waves originates at the origin, i.e. r=0 ... which I assume can't be right as you of course cannot divide by zero.
Thanks!

Hi
At university, in a previous module the constant in front of the Fourier Transform was given as (1/2π), and the constant in front of the inverse F.T. was 1.
However in a current module the lectrurer gives the constant as (1/√2∏), for both the F.T. and its inverse. Why is this?
Thanks
