Transverse inelastic form factors in 12C from a continuum model

Abstract

The transverse inelastic form factors in 12C, which appear in electron excitation of the giant resonance continuum states, were investigated. Using a particle-hole model the J π = 1 − form factor was calculated assuming the particle lies in the continuum. It was found that as momentum transfer increases the peak of the resonance shifts in energy. The integrated form factor was calculated and showed the characteristic dip with increasing momentum transfer. In addition, it was found to be roughly 70% of that calculated using bound state wave functions for the excited states.
