Figure 1

In this figures are display the imaginary part against the real part of the energy eigenvalues of the Richardson's neutron pairs, for ${}^{174}\mathrm{Yb}$. The different figures, from (a) to (f) are the results obtained for increasing values of the deformation parameter δ. Notice that for the pairs with lower energies, the eigenvalues are reals, but the imaginary part, related to the collectivity of the pairs, begins to increase as the energy approach the fermi level.Reuse & Permissions
