Nuclear Spin and Angular Momentum: Nucleus consists of two kinds of particles - protons and neutrons. They are both spin 1/2 particles and have an intrinsic Spin-Angular momentum. Also, in some Nuclear models, like the Shell Model, the nucleus is assumed t o have a Central-potential field. In such a central potential, the solutions of the SE will lead to quantum numbers such as the azimuthal quantum number, thus leading to orbital Angular Momentum for these particles.
Thus, the nucleus is composed of particles that not only have spin angular momentum, but also orbital angular momentum. This contributes towards the Spin angular momentum of the Nucleus as a whole. The Nucleus then behaves as a singular particle with its own Spin Angular Momentum, that has a certain magnitude and direction that is quantised by similar rules.
Whether there is an even or odd number of protons or neutrons also plays a role in determining what is the Nuclear spin, since such particles tend to pair up with each other and cancels each others spin.
