A Precision Measurement of the Neutron Scattering Length of He-4 Using Neutron Interferometry

R. Haun, F. E. Wietfeldt, M. Arif +5

We report a 0.08 % measurement of the bound neutron scattering length of He using neutron interferometry. The result is $b = (3.0982 \pm 0.0021 \mbox{ [stat]} \pm 0.0014 \mbox{…

Experimental Upper Bound and Theoretical Expectations for Parity-Violating Neutron Spin Rotation in 4He

H. E. Swanson, C. D. Bass, T. D. Bass +16

Neutron spin rotation is expected from quark-quark weak interactions in the Standard Model, which induce weak interactions among nucleons that violate parity. We present the result…
