Description

I will discuss the importance of the T20 quantity and the basic experimental setup for a measurement of d (γ, n). Multiple measurements have suggested the existence of a channel around 9 MeV above the two nucleon masses in the center of mass frame. This diverges from calculations from current nuclear theory, and this experiment will focus on this new channel and yield information on the nature of any discrepancy. This experiment will immediately follow the experiment on the GDH measurement of the deuteron and use a lot of the same equipment. While the target will be polarized in the GDH experiment, the target will have the tensor component enhanced for the T20 experiment. I will discuss the status of the experiment, as well as the current status of the dilution refrigerator, and the progress being made.
