Energy Level diagram for a spin-1/2 nucleus as a function of
... The z-component of the nuclear angular momentum is related to the z-component of the nuclear spin. Recall in quantum mechanics that a total angular momentum of L has 2(L+1) components. The same is true for nuclear angular momentum and hence spin. (this gives rise to the different orbital structures) ...

Experiments that revealed the Structure of the Atom
... Rutherford and his team (Geiger and Marsden) bombarded a number of different thin metal foils with alpha (α) particles from a radioactive source. Alpha particles are tiny, heavy particles with a positive charge. Particles passing through the foil would strike a screen coated with zinc sulfide, and a ...

PP Mass spectrometer and atoms
... The first mass spectrometer was built in 1918 by Francis W Aston, a student of J J Thomson, the man who discovered the electron. Aston used the instrument to show that there were different forms of the same element. We now call these isotopes. In a mass spectrometer, particles are turned into positi ...
