“…Numerous methods for the neutron polarization analysis have been developed, for instance, using polarizing supermirrors [3][4][5] or polarized 3 He [6][7][8][9]. We propose a new complementary method based on P -even asymmetry in reactions of polarized neutrons with nuclei.…”

A new method to measure polarization of cold/thermal neutrons using P -even asymmetry in nuclear reactions induced by polarized neutrons is proposed. A scheme profiting from a large correlation of the neutron spin and the circular γ-quantum polarization in the reaction (n, γ) of polarized neutrons with nuclei is analyzed. This method could be used, for instance, to measure the neutron-beam polarization in experiments with frequently varying configuration. We show that high accuracy and reliability of measurements could be expected.

The beta decay of the free neutron provides several probes to test the Standard Model of particle physics as well as to search for extensions thereof. Hence, multiple experiments investigating the decay have already been performed, are under way or are being prepared. These measure the mean lifetime, angular correlation coefficients or various spectra of the charged decay products (proton and electron). NoMoS, the neutron decay products momentum spectrometer, presents a novel method of momentum spectroscopy: it utilizes the R × B drift effect to disperse charged particles dependent on their momentum in an uniformly curved magnetic field. This spectrometer is designed to precisely measure momentum spectra and angular correlation coefficients in free neutron beta decay to test the Standard Model and to search for new physics beyond. With NoMoS, we aim to measure inter alia the electron-antineutrino correlation coefficient a and the Fierz interference term b with an ultimate precision of ∆a/a < 0.3% and ∆b < 10 −3 respectively. In this paper, we present the measurement principles, discuss measurement uncertainties and systematics, and give a status update. * Neutron Beta Decay in the Standard ModelThe beta decay of the free neutron is well described within the V-A theory of the SM. Fermi's Golden Rule for the neutron's decay rate yields the following insightful correlation between the mean lifetime τ n , the weak axial-vector coupling constant g A and V ud [3]: arXiv:1906.04511v1 [physics.ins-det]
