Question

Two angular momenta whose quantum numbers are l1= 1 and l2= 2are added to give a summed angular momentum j. Identify ALL of thefollowing statements about the summed angular momentum that aretrue. 1. There are three different possible values for the quantumnumber of the summed vector.

2. The minimum possible value of j iszero.

3. The maximum possibleprojection of j along a particular direction in space is 3 hbar.(hbar is equal to Planck's constant divided by2*3.14159).

4. The minimum possible valueof j is -1.

5. The maximum possiblemagnitude of the vector J is equal to sqrt(6)hbar.
