How Is Nuclear Spin Calculated for Alkali Atoms?

[kawkaw]

hello,
i am new in this forum , :) i want to ask if anyone know how to calculate the nuclear spin of an atom in general, i searched in google i didnt find any method of calculation :/
can anyone help me please, thanks

If it's even-even, it's spin-0. Otherwise, there is no general rule.

If the number of nucleons is odd then the spin is half-integer - but which half-integer varies widely with the shell structure of nuclei.

If the nucleus is odd-odd then the spin is integer - but ground state rarely has zero spin. Checking, just found a counterexample (manganese 50).

This is the realm of nuclear structure calculations. See for example, the nuclear shell model. Without doing complicated calculations, you can use the Nilsson Model to find the spin and parity of single particle states.

ETA2: If you just want to look up the ground state spins, you should look at NNDC. http://www.nndc.bnl.gov/chart/
