|Title:||Precision Measurement of the Neutron-3He Spin-Dependent Scattering Length Using Neutron Interferometry|
|Published:||May 22, 2009|
|Abstract:||There is strong theoretical interest in the study of few-body nucleon systems. Experimental measurements of neutron scattering lengths are able to perform precise tests of nucleon-nucleon models. Neutron interferometry provides some of the most precise values of spin-independent neutron scattering lengths, bc, including measurements for n-H, n-D, and n-3He to better than a percent relative uncertainty. The spin-dependent neutron scattering length, bi, of n-3He has been measured once before by Zimmer et al. using a polarized helium-3 target inside a spin echo apparatus.|
