using the quasifree 
reaction at 
MeV.
Data were collected at several different momentum transfers ranging from
to 
. The experiments were
carried out at The Indiana University Cyclotron Facility (IUCF) using the
swinger experimental area and the INPOL and KSU neutron polarimeters.
The observables are used to determine the ratio of the spin longitudinal
nuclear response function to the spin transverse nuclear response function
.
Recent similar measurements done at 
MeV at the Los Alamos Meson
Physics Facility (LAMPF) seem to indicate that the predicted enhancement of
this ratio in the quasifree region does not exist. This discrepancy
led to a lot of theoretical interest and several new predictions have been
made regarding the ratio, 
. These
include some ``exact'' calculations made using Faddeev techniques and
Green's function Monte Carlo (GFMC) techniques, the latter predicting that
the enhancement should exist but that it would be distributed away from the
quasifree peak and it should be noticeable even in very light nuclei
(i.e. 
, 
).
These 
experimental data agree more
closely with the
results from GFMC calculations than those from the Faddeev calculations,
which may indicate that certain nuclear medium effects, such as high order
correlations, are already important in few-body systems.
The 
data is consistent with the results at 
MeV.
