The lower-energy states in a covalently bound diatomic molecule can be found approximately from the so-called Morse potential \(U(r)=U_{0}\left(e^{2\left(r-r_{0}\right) / a}-e^{-2\left(r-r_{0}\right) / a}\right),\) where \(r\) is the atomic separation and \(U_{0}, r_{0},\) and \(a\) are constants determined from experimental data. Calculate \(d U / d r\) and \(d^{2} U / d r^{2}\) to show that \(U\) has a minimum, and find expressions for (a) \(U_{\min }\) and (b) the separation \(r_{\min }\) at the minimum energy.
Suppose a room-temperature superconductor were discovered. but it had a very low critical field. In what way would this limit its practical applicability?
Why is the exclusion principle crucial to the existence of stable molecules?
