Examples:
2D5/2 | it's said: doublet D five second |
the state with S = 1/2, L = 2 and J = 5/2 |
|
6H13/2 | it's said: sextet H thirteen second |
the state with S = 5/2, L = 5 and J = 13/2 |
|
1S0 | it's said: singlet S zero |
the state with S = 0, L = 0 and J = 0 |
The kinetic moments S = 1 and L = 1 can principally give total kinetic moments J = 0, 1, 2. The possible states are then the following ones:
