The track structure of low energy electrons (with minimum energy of 1eV) in water as a media has keen simulated with Monte Carlo method, taking into account inelastic processes such as ionization, excitation, attachment and auto ionization caused by super excitation, and the yield and distribution of some free radicals.

LEEM has high lateral (15nm) and longitudinal (atomic) resolution, and can be easily combined with low energy electron diffraction or some other form of microscopy.

Based on our Monte Carlo calculation model, frequency distributions of energy deposition in areas of DNA segment and chromatin fibre segment by a low energy electron are calculated in liquid water.

Studies on the momentum transfer cross sections for low-energy electron scattering by nitrogen molecule;

The apparatus based on the techniques of trochoidal electron monochromator and quadrupole mass filter can be used for investigations of dynamics processes of the low-energy electrons interacting with molecules.

The refraction effect of metallic potential well on low energy electron beam diffraction is investigated and a new method for measuring the depth of metallic potential well is given by using low energy electron diffraction.

Poly(D,L-lactic acid)-co-poly(ethylene glycol)copolymer(D,L-PLEG)synthesized by melt poly- condensation was irradiated using low energy electron beam(EB)in the presence of triallyl cyanu- rate(TAC)and tetraallyl pentaerythritol(TAPE)as crosslinking agents.

AUTOMATED TENSOR LEED DETERMINATION FOR SURFACE STRUCTURE;

The atomic structure of the clean CZT(110) surface obtained by Ar+ etching in vacuum was observed through low-energy electron diffraction(LEED),where no surface reconstruction was discovered.
