EXPLANATION OF WHY THE RESONANT STRUCTURE SEEN IN THE (1+1) REMPI SPECTRUM OF Kr$\cdot$NO VIA THE $\tilde{A}^{2}\Sigma^{+}$ STATE APPEARS IN THE $Kr^{+}$ MASS CHANNEL AS WELL AS THE Kr$\cdot$$NO^{+}$ MASS CHANNEL

Abstract

The (1+1) REMPI spectrum of the $\tilde{A}^{2}\Sigma^{+}$ state of Kr$\cdot$NO appears not only in the Kr$\cdot$$NO^{+}$ channel, as would be expected, but also in the $Kr^{+}$ channel; this is despite the fact that the ionization energy of Kr is such that three photons of the laser used would need to be absorbed in order to produce these ions. Four mechanisms are considered: Two presented previously by $Miller^{a}$ and two novel mechanisms. All the mechanisms have pros and cons, and these will be detailed in the talk.
