Parametrizations of total cross sections sucient for all channels of the πB → Y K reactions are completed using a resonance model. As well as discussing the πN → ΛK reactions, which were not presented in our previous publications, we present the differential cross section for πN → ΛK. This report also aims at presenting supplementary discussions to our previous work.

Theoretical Results

The Lorentz-invariant differential cross section (LIDCS) for π production in heavy ion collisions was studied through the two-step process, NN→NΔ→NNπ. A phenomenological interaction potential containing central and tensor terms was used. The effect of inclusion of the tensor term on the LIDCS was little. The target nucleus 12C was excited to one of its giant resonance states, Jπ=1+, T=1, while the projectile nucleus 16O was excited to an isobar Δ (M=1232 MeV , ΓΔ=115.11 MeV ) which decayed (NΔ→NNπ), giving a nucleon and a pion mπ=138 MeV . In comparison with available experimental data, the shape was reproduced, but the theoretical results were higher.

Collision Processes

Calculations for cross sections for some states of Ne excited by electron impact have been carried out. A parametrization of total and differential cross section in the Born–Ochkur approximation has been proposed. Using this parametrization and appropriate wave functions for the states involved in the collision processes, differential and total cross sections have been calculated. The results have shown that this parametrization is very convenient to study this type of problem.

Differential cross sections for elastic scattering and ionization in positron–argon collisions as a function of energy (40–150 eV) are reported at 60°. Of particular interest is the energy range 55–60 eV, where earlier measurements by the Detroit group found a drop in the elastic-scattering cross section of a factor of 2. This structure has been tentatively attributed to a cross channel-coupling effect with an open inelastic-scattering channel, most likely ionization. Our results indicate that ionization remains an important channel over the same energy range and only begins to decrease at an energy above 60 eV.
