How to find an orthogonal quantum state? [closed]

In the question I have L = 1 and s = 1/2. First I had to find the quantum state for the highest m = m$_l$ + m$_s$ value which I did. To find the quantum states for the next highest m value I used the …

What are the 'good' quantum numbers for the weak- and strong-field Zeeman effect?

I'm quite confused on the 'good' quantum numbers. I thought the good quantum numbers could be defined as the quantum numbers which corresponding operators commute with each other and the Hamiltonian. …

How to find the direction for which the single spin is 1? [closed]

I have the state $\left|\psi\right.\rangle = \alpha\left|\right.0\rangle + \beta\left|\right.1\rangle$. I want to show that there is a direction $\vec{n}$ for which the spin is $+1$, so $\langle\vec{n …

When creating term symbols, how do you know if the angular momentum $L$ is antisymmetric of ...

For example I'm trying to get the term symbol of $(1s)^{2}(2s)^{2}(2p)^2$ . In the answers they state the following: The combination of angular momenta $L_1 = L_2 = 1$ gives $L = 2$ (symmetric) …
