FIG. 1.

(a) Velocity profile and (b) kinetic energy distribution of emission following UV laser excitation at 6.4 eV. The hyperthermal kinetic energy distribution peaks near 0.35 eV (b). The dashed line in (b) displays the half-range Maxwell–Boltzmann distribution expected for room temperature thermal desorption.

FIG. 2.

(a) Velocity profile and (b) kinetic energy distribution of emission following UV laser excitation at 6.4 eV. The hyperthermal kinetic energy distribution peaks near 0.25 eV (b).

Image of FIG. 3.
FIG. 3.

(a) Velocity profile and (b) kinetic energy distribution of emission following UV laser excitation at 7.9 eV. The hyperthermal kinetic energy distribution peaks near 0.35 eV (b). The dashed line in (b) displays the half-range Maxwell–Boltzmann distribution expected for room temperature thermal desorption.

Image of FIG. 4.
FIG. 4.

Velocity profile and kinetic energy distribution of emission following UV laser excitation at 7.9 eV. The dashed line in (b) displays the half-range Maxwell–Boltzmann distribution expected for room temperature thermal desorption. The hyperthermal distribution appears as a shoulder on the high-energy side of the thermal desorption component.

FIG. 5.

Schematic potential energy curves for the excited states correlating to (1) , (2) , and (3) desorption from the KI (100) surface and respective formation of surface -centers or a charged vacancy . The crossing points between curves (1) and (3) and curves (2) and (3) are indicated by and , respectively. See text for details.
