Abstract

We report the first results from a new approach for measuring the He3 neutron incoherent scattering length bi. bi is directly proportional to the difference Δb=b+−b− in the two low-energy s-wave neutron-nucleus scattering amplitudes b+ and b−, corresponding to the singlet J=0 and triplet J=1 states of the neutron-He3 interaction, respectively. An accurate measurement of bi can help distinguish among different models of three-nucleon interactions by comparison to ab initio nuclear theory calculations. The neutron birefringence caused by Δb results in neutron spin rotation around the nuclear polarization. We measured Δb using polarized neutron spin rotation and the transmission of neutrons through a He3 gas target polarized in situ by spin-exchange optical pumping. This brief test measurement performed on the J-NSE Phoenix neutron spin echo spectrometer, yielded Δb=[−5.27±0.05 (stat.) −0.05 (syst.)] fm. We argue that this method can be improved in precision to resolve the discrepancies between two prior measurements of bi which are dependent on the polarized absorption cross section σp. With absolute He3 polarization measurement via nuclear magnetic resonance (NMR) (in a properly shaped cell) concurrent with accurate neutron transmission measurements, σp can be measured to obtain independent values of b+ and b−.
