  A new measurement of $\Delta\sigma_T$ for polarized neutrons transmitted
through a polarized proton target at 16.2 MeV has been made. A polarized
neutron beam was obtained from the $^{3}\rm{H}(d,\vec n)^{4}\rm{He}$ reaction;
proton polarization over 90\% was achieved in a frozen spin target of 20 cm$^3$
volume. The measurement yielded the value $\Delta\sigma_T=(-126\pm21\pm14)$ mb.
The result of a simple phase shift analysis for the $^3S_1-^3D_1$ mixing
parameter $\epsilon_1$ is presented and compared with the theoretical potential
model predictions.
