Use the shell model to determine the parity and spin assignments for all the stable isotopes of calcium.
The Attempt at a Solution
The stable isotopes seem to be 40Ca, 42Ca, 43Ca, 44Ca, 46Ca, and 48Ca
I believe all of those isotopes except 43Ca are even-even which means that they have spin=0 and parity=even, however I'm a bit stuck on how to work out the spin and parity of 43Ca.
There are 23 neutrons, so 20 of those fill up the shells to the magic number (20) and we have 3 left over.
How do I work out the orbital angular momentum l and j-value of those?
With these values I could work out the spin of the unpaired nucleon (which would be the j-value) and its parity (-1)l
