The discrete scaling can be identified by the energy dependence of an atom-molecule elastic cross-section, when colliding a heavy atom with mass (formula presented) into a weakly-bound heavy-light ((formula presented)) dimer. In the extreme mass-imbalanced system it was verified that the s-wave elastic cross section presents zeros at several specific energies of the projectile, in which emerges a discrete behavior from the ratio between these energies. This discrete behavior is identified with the same one predicted for the trimer excited bound-states, when considering the same mass-imbalanced system in the unitary limit.15-19engTrabalho apresentado em evento10.1007/978-3-030-32357-8_32-s2.0-85078448873
