  There are two available set of data on the $e^+e^- \rightarrow \Lambda^+_c
\bar{\Lambda}_c^-$ cross section above threshold. The BELLE measurement, with
ISR return, is compatible with the presence of a resonant state, called
$\psi(4660)$ (formerly known as $Y(4660)$), observed also in other final
states. The BESIII dataset has shown a different trend, with a flat cross
section. We propose a new solution to fit both datasets by means of a strong
correction to the Coulomb enhancement factor. Mass and width of the resonant
state is extracted.
