Out-of-Plane Measurements of the Structure Functions of the Deuteron -
We now know that particles called quarks are the basis for the atoms, molecules, and atomic nuclei that form us and our world.
Nevertheless, how these quarks actually combine to form that matter is still a mystery.
The deuteron is an essential testing ground for any theory of the nuclear force because it is
the simplest nucleus in nature. In this project we use the unique capabilities
of the CLAS detector at
Jefferson Lab to make some of the first
measurements of little-known electric and magnetic properties of the deuteron. In the past
scattering experiments like those done at JLab were confined to reactions where the debris
from the collision was in the same plane (usually horizontal) as the incoming and outgoing
projectile (an electron in this case).
With CLAS we can now measure particles that are scattered out of that plane and are
sensitive to effects that have been often ignored up to now.
These measurements will open a new window into the atomic nucleus.
