I like music. I also enjoy finding out what we can understand, and knowing how it fits in a logical scheme.

 Sep24 awarded Autobiographer Mar23 awarded Supporter Mar12 comment Relationship between nuclear spin and nuclear magnetic moment? I don't think so, total angular momentum is clearly defined as the sum of angular momentum and spin. Mar12 comment Relationship between nuclear spin and nuclear magnetic moment? The source is Kenneth Krane's book 'Introductory Nuclear Physics'. $\langle s_j \rangle$ is the expected value for the $\vec{j}$-component of the spin vector, $\vec{s}$. We assume a fixed $z$ axis around which $\vec{j}$ -the sum of angular and spin momentum- rotates. In the book, it is said that if we want to measure $\langle s_z \rangle$, it suffices to know $\langle s_j \rangle$. Why? Mar12 asked Relationship between nuclear spin and nuclear magnetic moment? Feb5 comment Why is the value of spin +/- 1/2? I think it should be on the lines of your second option. Does it only have to do with the fact that $m_s$ is quantized on integer steps and only two states are seen in a Stern-Gerlach experiment (thus eliminating the possibility of $m_s=0$)? Feb5 comment Why is the value of spin +/- 1/2? I suppose it has to do with how we measure the eigenvalues for spin (perhaps multiples of bohr's magneton) Feb5 awarded Student Feb5 asked Why is the value of spin +/- 1/2?
