Positron scattering by beryllium atoms in the low-energy range (≤4.0 eV) was studied within ab initio and semiempirical frameworks. When interpreting the static dipole polarizability and the scattering length as representative quantities of the tar

Since total cross section measurements for electron scattering by Zn and Cd performed in the 1970s, the existence of p-wave shape resonances below 1 eV are well established in the literature. It was suggested that a second d-wave shape resonance coul

The insertion of modern and contemporary Physics topics on Brazilian High School Education is no longer something so distant. The didactic books approved in the last National Plan include, somehow, discussions about this theme. However, the effective

The aim of this work is to present and discuss the Ramsauer-Townsend effect in the context of low-energy positron scattering by rare gas atoms. Opposed to what happens in electron-atom scattering, the competition between the static repulsive and pola

We present positron scattering cross sections with C2H2 molecules obtained with the Method of Continued Fractions in the static plus correlation polarization level. The differential and integral cross sections are compared with available theoretical

We report an ab initio and model potential investigation of elastic and rotational excitation cross sections for positron impact with Li2 molecule in the energy range from 0.1 to 10.0 eV. The ab initio cross sections were calculated with the Schwinge
