Measurement of the Coherent Neutron Scattering Length of 3He
By means of neutron interferometry the s-wave neutron scattering length of the (3)He nucleus was re-measured at the Institut Laue-Langevin (ILL). Using a skew symmetrical perfect crystal Si-interferometer and a linear twin chamber cell, false phase shifts due to sample misalignment were reduced to a negligible level. Simulation calculations suggest an asymmetrically alternating measuring sequen...

متن کاملPrecision measurement of the n-3He incoherent scattering length using neutron interferometry.
We report the first measurement of the low-energy neutron-(3)He incoherent scattering length using neutron interferometry: b_{i};{'} = (-2.512 +/- 0.012 stat +/- 0.014 syst) fm. This is in good agreement with a recent calculation using the AV18 + 3N potential. The neutron-(3)He scattering lengths are important for testing and developing nuclear potential models that include three-nucleon forces...
متن کاملHigh-Precision Determination of the Neutron Coherent Scattering Length
The neutron coherent scattering length b c has been determined interferometrically to an uncertainty of about 5 × 10(-5) by measuring the nondispersive phase. We propose improving the uncertainty to about 10(-6) by optimizing various parameters of the interferometric experiment. Any uncertainty in the b c determination arising from possible variations in the constitution of the ambient air can ...
