N-N
STATES
L= O, 1, 2, 3, 4,
5,
L = S, P, D, F, G, H,
J = L+S; S= O
or 1
2S+1Lj is how NN states are specified
When S = 0, 2S+1 =1, Singlet States
When S =1, 2S+1= 3,
triplet States
L= 0, 2, 4,
Even & L= 1, 3, 5,
Odd States
1S0,1D2 ,1G4,
are leading even singlet
states
1P1 , 1F3 , 1H5 ,
are leading odd
singlet states
3S1-3D1
is the most interesting example of a coupled triple state.
It has the only bound NN Statethe deuteron.
