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

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. |

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? |

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 $m_s=0$)? |

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) |
