Test of Lorentz invariance in β decay of polarized ²⁰Na

RADIOACTIVITY ²⁰Na(β⁺)[polarized ²⁰Na source from ¹H(²⁰Ne, n), E=20 MeV/nucleon at AGOR-KVI cyclotron facility, polarization by optical pumping]; measured Eβ, Iβ, Eγ, Iγ, polarization, dependence of half-life of ²⁰Na nuclei on the nuclear spin direction; deduced no significant violation of Lorentz invariance (LIV) in weak interactions.
