Contour maps of the two-neutron densities $\rho (x,x,\theta )$, weighted by $8{\pi }^2{x}^4\sin \theta$, for the $0_1^{+}$ and $0_2^{+}$ states of ${}^{16}\mathrm{C}$. The contour shows peaks, and the difference between any two neighboring contour levels, is $0.01{\mathrm{fm}}^{-2}$. See text.Reuse & Permissions
