Fast-phonon induced broadening of single-particle lines in excited nuclear matter

Mostrar todas las versiones(2)

A modified kinetic equation for nuclear matter, whose generator of irreversible motion contains a contribution from coupling to a fast collective mode in addition to the usual kinetic kernel, is examined. The fermionic collision rates are evaluated in the relaxation-time approximation, assuming a fi...
