“…They should be affected much less by intracluster elastic scattering, as the respective cross sections have pronounced maxima at kinetic energies around 10 eV and drop by factors between 3 and 6 for an electron energy of 100 eV. 19 Consequentially, for the Xe 4d line of N = 270 clusters, Rolles et al 13 found identical β values between atoms and clusters, even in an energy range with a pronounced photoelectron anisotropy (photon energies 135-150 eV, kinetic energies 85-100 eV). On the other hand, the same authors found significantly lowered β values for Ar 3s of similar size Ar clusters at kinetic energies up to 70 eV.…”

The angular distribution of photoelectrons emitted from water clusters has been measured by linearly polarized synchrotron radiation of 40 and 60 eV photon energy. Results are given for the three outermost valence orbitals. The emission patterns are found more isotropic than for isolated molecules. While a simple scattering model is able to explain most of the deviation from molecular behavior, some of our data also suggest an intrinsic change of the angular distribution parameter. The angular distribution function was mapped by rotating the axis of linear polarization of the synchrotron radiation. [http://dx

Absolute differential elastic and vibrational excitation cross sections up to v = 11 were measured for CO in scattering angle ranges extending to 180 • at energies between 0.2 and 5 eV (and an elastic measurement at 10 eV). The lowest angles were 0 • for inelastic scattering and between 5 • and 20 • for elastic scattering, depending on energy. Integral cross sections were derived by integrating under the angular distributions and compared with previous beam and swarm measurements. The sum of the integral cross sections agrees very well with the available transmission measurements of the grand total cross section, thus validating the present measurements. The present elastic differential and integral cross sections are in excellent agreement with the best available measurement [Gibson et al., J. Phys. B 29, 3197 (1996)], but the v = 1 inelastic cross section is about 25% higher. This could have consequences for simulations of cometary and planetary atmospheres.

“…A wealth of information has been gained on the dynamics of these collisions, as documented by many reviews and books (e.g. Schulz, 1973a, b;Lane, 1980;Trajmar et al, 1983;Christophorou, 1984;Shimamura and Takayanagi, 1984;Allan, 1989;Domcke, 1991;Buckman and Clark, 1994;Crompton, 1994;Filippelli et al, 1994;Trajmar et al, 1994;Huo and Gianturco, 1995;Andersen and Bartschat, 1996;Chutjian et al, 1996;Zecca et al, 1996;Becker et al, 2000;Illenberger, 2000;Winstead and McKoy, 2000;Christophorou and Olthoff, 2001a, b;Karwacz et al, 2001a, b;Brunger and Buckman, 2002). In spite of this progress, however, the exploration of threshold phenomena in electronmolecule collisions at low energies -both in the limit of zero electron energy and in the neighborhood of onsets for vibrational excitation -has remained a major challenge for experiment and theory.…”

“…In the remaining part of Section I, we present a brief qualitative introduction into the field of low-energy electron-molecule collisions. Recent complementary surveys on electron collisions with molecules and clusters include several articles in journals (Hashemi et al, 1990;Domcke, 1991;Ma¨rk, 1991;Illenberger, 1992;Smith and Sˇpanel, 1994;Dunning, 1995;Chutjian et al, 1996;Ingolfsson et al, 1996;Zecca et al, 1996;Burrow et al, 1997;Field et al, 2001a;Karwacz et al, 2001a, b;Brunger and Buckman, 2002) and book chapters (Trajmar et al, 1994;Huo and Gianturco, 1995;Becker et al, 2000;Illenberger, 2000;Winstead and McKoy, 2000;Christophorou and Olthoff, 2001a,b;Hotop, 2001;Tanaka and Sueoka, 2001). …”
