✦ Synopsis

Ni: ions generated in a pulsed high-temperature plasma and cooled by supersonic expansion are photodissociated with tunable visible laser radiation. Resonant bound-bound absorption in the isolated ion is detected by the observation of Ni: +Ni+ + NI sequential two-photon dissociation. Progressions of vibronic bands with partially resolved rotational structure belonging to sev-era1 distinct electronic transitions in Ni+ 2 have been observed in the interval between 16250 and 23500 cm-'. The appearance and preliminary analysis of this resonant two-photon dissociation (RZPD) spectrum will be discussed.

We show that resonant two-photon versus two-photon interference provides a means of controlling relative photodissociation cross sections even when the initial molecular system is in a mixed state, e.g. in thermal equilibrium. The resultant technique, which also allows cancellation of incoherences d
