Class nucmass_ldrop_pair (o2scl)¶
-
class nucmass_ldrop_pair : public o2scl::nucmass_ldrop_skin¶
Liquid drop model with pairing.
This class adds a pairing correction
\[ E_{\mathrm{pair}}/A = - \frac{\zeta}{2 A^{3/2}} \left[ \cos(Z \pi) + \cos(N \pi) \right] \]where \( \zeta \) is stored in Epair. The trigonometric functions give the expected result for integer values of N and Z.Subclassed by o2scl::nucmass_ldrop_shell
