Abstract
We investigate strong and radiative meson decays in a generalized Nambu--Jona-Lasinio model. The one loop order calculation provides a satisfactory agreement with the data for the mesonic spectrum and for radiative decays. Higher order effects for strong decays of ρ and K* are estimated to be large. We also discuss the role of the flavour mixing determinantal interaction.
