Query: The Ratio of Gluon Distributions in Sn and C   We calculate the ratio of gluon densities, G^Sn(x)/G^C(x), for 0.01<x<0.1,
from the new high statistics data on F_2^Sn/F_2^C taken by the NM
Collaboration. For small x, the shadowing in the gluon distribution is about
equal to the shadowing of quark distribution. The antishadowing in the gluon
distribution, however, is roughly 10%. We also compare with the ratio
difference, R=sigma_L/sigma_T, from Sn and C.
