  We compute the quantum work distribution for a driven Morse oscillator. To
this end, we solve the time-dependent dynamics for a scale-invariant process,
from which the exact expressions for the transition probabilities are found.
Special emphasis is put on the contributions to the work distribution from
discrete (bound) and continuous (scattering) parts of the spectrum. The
analysis is concluded by comparing the work distribution for the exact Morse
potential and the one resulting from a harmonic approximation.
