From subarcsec-seeing infrared images and spectra in the K and H
bands, we present reflectivities and limb-darkening results for two of
the hazy regions generated during the SL-9 collision. These highly
reflective impact areas at methane infrared wavelengths have been
studied in terms of multiple scattering radiative models. The results
for both the H and D/G impact remnants show that a considerable amount
of particles have been injected in jovian stratospheric levels from
$\sim$1 mbar to the upper level of the assumed jovian tropospheric
NH$_3$ ice haze ($\sim$300 mbar). Our models suggest a concentration
of small particles, with mean radius of 0.15 $\mu$m for a real
refractive index of 1.7. The imaginary refractive indices are in the
range 1$\times$10$^{-4}$ to 1$\times$10$^{-3}$. For the H impact
region, absorption at 2.0 $\mu$m is enhanced compared to unperturbed
regions at the same scattering geometry. This enhancement is not
observed in the older D/G complex.
