Collins conjecture is examined in the dissociating molecules of ${\mathrm{H}}_{2}$ and ${\mathrm{N}}_{2}$, proportionality between correlation energy entropy exists region close to equilibrium bond length. Similar also kinetic entropy. On other hand, potential difference expands over a larger nuclear distance. The result suggests method estimate from eigenvalue spectrum 2-matrix discussed.

The use of Feshbach resonances for tuning the interparticle interaction in ultracold Fermi gases has led to remarkable developments, in particular to the creation and Bose-Einstein condensation of weakly bound diatomic molecules of fermionic atoms. These are the largest diatomic molecules obtained so far, with a size of the order of thousands of angstroms. They represent novel composite bosons,...
