... 8. Two (identical) electrons are bound in a Helium atom. What are the allowed states |j`s`1 `2 i if both electrons have principal quantum number n = 1? What are the states if one has n = 1 and the other n = 2? If an electron is in an n = 1 state, it can only have ` = 0 since ` < n for hydrogen state ...

... (b) Write down completeness and orthonormality relations for the ONB {| i}. Note that these states have both a continuous index and a discrete one, so that one has to do the correct kind of summation, and use the correct delta function for each index. (c) Express an arbitrary state vector |i ...

... Clearly, this has zeros when x1 = 0, L, when x2 = 0, L, and when x1 = x2 . If the particles were charged, they would repel each other through the Coulomb interaction. Therefore, in the spin 1/2 case, the triplet state would have the lower energy, because the particles tend to be further apart. This ...
