Femtosecond probing of nuclear motion in an alkali halide (NaI) reaction reveals a persistent wave packet, recurring at long times up to 40 ps. The detection of both "free" Na atoms and "transient" [Na...I] \* l indicates non-exponential dynamics through the crossing zone of the covalent and ionic p
