Question

In terms of the parameters describing interatomic interactions. Specifically, Morse potential contains three adjustable parameters, E_morse, a, r₀. Interatomic interactions are characterized by the minimum energy E_min, the distance, at which the energy is minimum, r_emin, and the distance between atoms, at which attractive force is maximum, r_fmax. Express E_min, r_emin, and r_fmax in terms of E_morse, a, r₀. This implies that you write three formulas expressing E_min, r_emin, and r_fmax in terms of E_morse, a, r₀. To solve this problem, you will need to take into account that force f(r) = - dE/dr, where r is the distance between atoms.
