Field Dissociation by Atomic Tunneling of Compound Ions : Isotope and Orientational Effects
نویسنده
چکیده
Dissociation of HeRh2+ in high electric field occurs by tunneling of a neutral He out of the ion. This tunneling process occurs most readily when it is rotated 180. from its desorbed orientation. This rotation time is measured to be 790221 fs. The tunneling effect is supported by a very strong isotope effect observed when 4 ~ e is replaced by 3 ~ e , and also by a WKB calculation of barrier penetration probabilities.

THE EFFECTS OF VIBRATIONAL AND ROTATIONAL MOTION ON THE FIELD DISSOCIATION BY ATOMIC TUNNELING OF HeRh2 IONS
When a compound ion is placed in an intense electric field, the potential banier may be lowered to the extent that dissociation can occur via quantum mechanical tunneling (1). We have made a numerical study of the detailed atomic process of dissociation. When the molecular ion, Helth2+, is field evaporated from the surface, it cannot dissociate since it is in the wrong orientation. As the molec...
متن کاملIsotope effects and bond softening in intense-laser-field multiphoton dissociation of H2+
Isotope efFects in the Hz+-Dz+ fragmentation by intense laser fields o6er the possibility of a multiphoton interpretation of the bond-softening mechanism. Surprisingly, the calculations indicate that the one-photon dissociation of D&+ is favored with respect to that of H&+. This cannot be understood, as has previously been done, by a single-photon mechanism following tunneling through a lowered...
متن کاملMultiple recapture of electrons in multiple ionization of the argon dimer by a strong laser field.
We observe multiply frustrated tunneling ionization-induced dissociation of the argon dimers by intense linearly polarized ultrashort laser pulses. By measuring the kinetic energy release and angular distribution of the Coulomb explosion of up to eightfold ionized argon dimers, we can trace the recapture of up to two electrons to Rydberg states of the highly charged compound at the end of the l...
متن کاملOrientational anisotropy in oxygen dissociation on Rh„110..
Scanning tunneling microscopy study of O2 dissociation on Rh~110! at 170 K shows a low-energy dissociation coordinate for a precursor with the O-O axis aligned in the @001# azimuth, indicating a strong influence of the surface anisotropy on the potential-energy surface. This results in pairs of oxygen atoms oriented along @001#, which aggregate in chains along @11̄0# . The atomic distance in the...
متن کاملA MODEL STUDY OF LASER ISOTOPE SEPARATION BY PHOTOIONIZATION OR PHOTODISSOCIATION PROCESS
In this study, the selective photoexication of isotopic mixtures by laser light is investigated. Atomic and molecular methods are examined and rate equations are derived for both cases. Two and three step photoionization techniques are considered and rate equations are solved for ion yields. The molecular photodissociation process is also studied and the dependence of the dissociation produ...
