The inelastic scattering of electrons on weakly-bound nuclei is studied with a simple model based on the long range behavior of the bound state wavefunction and on the effective-range expansion for the continuum wavefunctions. Three…

The electromagnetic potential is the only force relevant to understand polyelectrolytes and it should enables us to reveal all polyelectrolytes properties. We argue that dielectric spectroscopy probes the average dipole moment of the pure…
