    Understanding the Shell Model in Nuclear Physics

    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...

    Optics: Interference - Calculate Order of Maximum Intensity

    “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...

    Beta-Decay Energy: Li-11 Q=20 MeV & Calculations

    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...

    Solutions To Spherical Wave Equation

    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!

    Solutions To The Spherical Wave Equation

    Te exponential approaches 1 and you have A/r, the same problem? Can you just tell me I'm running out of time here!

    Fourier Transforms - what's the constant?

    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
