External Relations and Sovereignties,t work by other groups in this area has been concerned with electron transmission through oxygen (Stephen and Burrow 1986; Zecca et al.1986). The present paper reports electron scattering by a supersonic beam of oxygen and appear to be the first crossed-beam study since that of Linder and Schmidt (1971).

The method has been further refined to consider other atomic processes and there is now a well developed suite of computer programs to perform R-matrix calculations on atoms and ions for a great number of processes, Burke (1987).

okyo.. Interesting studies, though limited to photographic measurements, were done with the synchrotron. With the advent of the dedicated 400 MeV storage ring (SOR-RING) at the University of Tokyo., more demanding experiments, e.g. photoelectron spectroscopy., lifetime measurements by fluorescence.,

They play a particularly important role in vibrational excitation producing dramatic enhancement of the cross sections at energies of a few eV which can take on various forms depending on their lifetime. Long lifetime resonances give sharp s

A. J. M. Milne Ph.D., B.Sc. (Econ.)case, an electron or a photon) is relatively small, ie just greater than the threshold energy of the reaction. Further, one or more electrons of very small energy (≤.01eV) can be produced. These conditions can have a profound influence on the collision. For example electron exchange can take place a
