Neutrino Nucleus Elastic scattering ( υA el ) is a well understood Standard Model process. A generic scale of E υ <50 MeV is usually taken to characterize the requirement of coherency in vA el process. To quantify this transition, we formulated a universal parametrization of the degree of coherency. The TEXONO experiment is pursuing measurement of the υA el interactions with the reactor neutrinos at Kuo-Sheng Reactor Neutrino Laboratory (KSNL), in a kinematic regime where the Quantum Mechanical coherency is complete. Point-contact germanium detectors at sub-keV sensitivities are adopted to detect the low-energy nuclear recoils in υA el . We report our latest status and plan of this program. A complementing line of research is on the formulation of a universal scheme to quantify the QM coherency effects in υA el , and study their dependence on experimental configurations. Constraints from existing measurements from COHERENT experiment are presented.
