On a recent calculation of the mass spectra of quarkonia using the Cornell potential with spin-spin interactions
Francisco M. Fernández
We analyse a recent application of the Cornell potential with spin-spin interaction to the mass spectra of quarkonia and show that the authors have in fact used the Kratzer-Fues po…

On some one-dimensional quantum-mechanical models with a delta-potential interaction
Francisco M. Fernández
We discuss a systematic construction of dimensionless quantum-mechanical equations. The process reduces the number of independent model parameters to a minimum and, at the same tim…
