in Semi-Inclusive Deep-inelastic Scattering using a Transversely
Polarized 3He Target"</b></font>
<br>
<br>
We recently measured the neutron target single spin asymmetry in the
<br>
semi-inclusive deep inelastic 3He(e,e'pi)X reactions with a
transversely
<br>
polarized 3He target. The experiment was performed at Jefferson Lab
Hall A
<br>
from October 2008 to February 2009. The pions were detected in the
<br>
high-resolution spectrometer in coincidence with the scattered
electrons
<br>
detected by the BigBite spectrometer. The kinematic coverage focuses on
<br>
the valence quark region, x = 0.13 to 0.41, at Q2=1.31 to 3.10 GeV2.
Data
<br>
from this experiment, when combined with data from HERMES and COMPASS
<br>
experiments, will provide constraints on the quark transversity and
Sivers
<br>
distributions on both u-quark and d-quark in the valence region.
