A certain atom is in the state in which `S=2`, the total angular momen

1.	A certain atom is in the state in which `S=2`, the total angular momentum `sqrt(2 ħ)`, and the magnetic moment is equal to zero. Write the spectral symbol of the corresponding term.
Answer» From `M= ħsqrt(J+1)=sqrt(2 ħ)` we find `J=1`. From the zero value of the magnetic moment we find `g=0` or `1+(1xx2L(L+1)+2xx3)/(2xx1xx2)=0` `1+(-L(L+1)+8)/(4)=0` or `12=L(L+1)` Hence `L=3`. The state is `.^(5)F_(1)`.
