- Abstract
- Electron capture processes by protons from highly charged
hydrogenic ions in dense plasmas including dynamic screening effects are
investigated using the semiclassical version of the Bohr-Lindhard model with the
straight-line path. The dynamic interaction potential in dense plasmas
is obtained by considering the longitudinal component of the plasma
dielectric function. The scaled semiclassical electron capture
probability is obtained as a function of the impact parameter, Debye length, and
projectile velocity. The dynamic plasma screening effect on the scaled
semiclassical electron capture probability is found to be more
significant for low projectile velocities. When the projectile velocity is smaller
than the electron thermal velocity, the dynamic screening effect is
weaker than the static screening effect. However, when the projectile velocity
is greater than the electron thermal velocity, the dynamic plasma
screening effect leads to the static plasma screening effect.
