Measurement of the parity-violating asymmetry in the reactions of cold polarized neutrons and light nuclei 6Li, 10B

Search and Measurement of P-Odd Asymmetry in the Emission of Secondary Particles Produced in Reactions of Polarized Thermal and Cold Neutrons with Light Nuclei

“…Yet another theoretical approach consists in expanding the parity-violating NN interaction in powers of the small parameter 1/N c where N c denotes the number of quark colors [12,13]. In this approach, the neutral current coupling constant f π is predicted to be significantly smaller than the charged-current coupling constant as indeed observed experimentally [14][15][16][17][18]. For this reason, it is particularly interesting from the viewpoint of our measurements reported in this paper.…”

A method to measure neutron polarization using P-even asymmetry of γ-quantum emission in the neutron-nuclear interaction

“…Potential applications include measurement/monitoring of the neutron beam polarization in experiments with frequently varying configuration, which are typical, for instance, for neutron instruments devoted to fundamental particle physics [10]: to give examples: * The text was submitted by the authors in English. 1 [ [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]; applicability of this method to experiments demanding the highest precision in the neutron polarization analysis, like to precision studies of the neutron β decay [27] has to be studied.…”
