114SN c 2009Wa22: Precise measurement of |b-asymmetry parameter.
114SN c {+114}In source obtained from IT decay of 49.5-d {+114m}In.
114SN2c Measured |b(|q,H,t); deduced |b-asymmetry parameter.
114SN3c Low-temperature nuclear orientation method combined with
114SN2c analysis by GEANT4 simulation code.
114SN3c {+114}In sample was implanted in Fe foil, then cooled to milli-kelvin
114SN4c temperatures in a strong magnetic hyperfine field induced by a
114SN5c superconducting split-coil magnet. The |b particles were detected with
114SN6c two planar HPGe detectors placed at 0|' and 90|' to the magnetic field.
114SN7c The |g rays were observed with two large volume HPGe detectors
114SN c 1969Co04: |g, semi ; |b, |b shape factor s
114SNxc (1961Da01,1961Ni02,1964An12,1964Da16,1973Bo43);
114SNxc bremsstrahlung endpoint (1969Ko29)
