Description

We will present a retrospective account of the TEXONO program on coherent neutrino nucleus scattering at the Kuo-Sheng Reactor Neutrino Laboratory in Taiwan with sub-keV germanium ionization detectors 1. The latest limits 2 and the various spinoff-impacts 3 will be discussed. We would provide updates on quantifying the quantum-mechanical coherency effects of the interactions 4. Efforts to continue and expand the program with reactor laboratories at the Sanmen Reactor in China will be summa-rized 5.
