The available experimental and theoretical cross section data for inelastic collision
processes of ground (3s) and excited (3p, 4s, 3d, 4p, 5s, 4d, and 4f) state Na atoms with …

We have carried out distorted wave calculations for electron impact 5 ^2\rmS→5 2 P, 6 2 S
and 4 2 D excitations of rubidium atom at incident electron energies in the range of 10-200 …

An experimental investigation of electron-impact excitation of the-state from the laser-excited
state of atomic sodium is reported for 30 eV incident electron energy. A detailed …

A systematic theoretical study is carried out for the electron and positron impact excitation of
the 3 1, 3 P and 3 1, 3 D states of helium from the ground 1 1 S state. The results are …

We discuss three different experiments for studying electron-excitation of atoms where
lasers have been used in combination. These are stepwise electron–photon excitation …

Recently we applied non-relativistic distorted wave approximation theory to study electron
impact excitations in lighter atoms (viz. hydrogen, helium and some alkalis). Excitations from …

In recent years, the developments in fusion plasma physics have been very promising and
gradually paving the way for a nuclear fusion power plant. The detailed knowledge of the …
