... Hamiltonian, including spin-orbit coupling. The operators Lˆz , Sˆz do not commute with the spin-orbit term in Ĥ , and should then not be used to label the states. We can construct common eigenfunctions, which we can give quantum numbers n, L, S , J , M J . The splitting due to spin-orbit coupling ...

... to allow for all possible numbers of particles, not just N particles. Of course we don’t need to do this, because the Hamiltonian conserves the number of particles, and all its matrix elements connecting states with, say N particles to states with N + 1 particles will be zero. Moreover, this is a bi ...

... The term Kab is called the Coulomb integral. Here, H0 = −(~2 /2m)4 + V (r) is the single electron part of the Hamiltonian. In summary, we have found that the energy of the two electron system, which is described by a spin-independent Hamiltonian is given by Ea + Eb + Kab + Jab when the two electrons ...

... rest mass energy. On contrary Klein-Gordon equation can account for rest mass energy but does not have potential energy term for fields other than electromagnetic fields. Thus there is a need to find a new quantum equation that accounts for rest mass energy, beside potential energy. This can be done ...

... The wavefunctions, y, themselves have no direct physical significance, rather it is the |y|2 which is physical – this represents the electron probability distribution and is the probability of finding the electron at any point around the nucleus. This function gives rise to the ‘shapes’ of the orbi ...
