  We report the results from a systematic study of the quasi-elastic (e,e'p)
reaction on $^{12}$C, $^{56}$Fe and $^{197}$Au performed at Jefferson Lab. We
have measured nuclear transparency and extracted spectral functions (corrected
for radiation) over a Q$^2$ range of 0.64 - 3.25 (GeV/c)$^2$ for all three
nuclei. In addition we have extracted separated longitudinal and transverse
spectral functions at Q$^2$ of 0.64 and 1.8 (GeV/c)$^2$ for these three nuclei
(except for $^{197}$Au at the higher Q$^2$). The spectral functions are
compared to a number of theoretical calculations. The measured spectral
functions differ in detail but not in overall shape from most of the
theoretical models. In all three targets the measured spectral functions show
considerable excess transverse strength at Q$^2$ = 0.64 (GeV/c)$^2$, which is
much reduced at 1.8 (GeV/c)$^2$.
