Look Up Calculated Ground-State
Proton and Neutron Pairing Gaps


 Pairing gaps calculated in the Lipkin-Nogami pairing model are looked up. For details please consult references
  • Nuclear Physics A536 (1992) 20
  • Atomic Data and Nuclear Data Tables 59 (1995) 185
We look up the pairing gap Δ and the number-fluctuation constant λ2 which are both obtained by solving eqs. (6)-(10) in the Nuclear Physics reference. We also tabulate

ΔLN= Δ + λ2

which is the quantity that should be identified with odd-even mass differences.


Write proton number Z:

Write mass number A:
