Neutrino-nucleus elastic scattering (νAel) is a well defined process in Standard Model of Particle Physics. It provides a unique laboratory to study the quantum mechanical coherency effects in electroweak interactions. We present an analytical formulation to quantify the coherency effects, relate this to nuclear form factors and experimental cross-section ratios, and characterize how its energy dependence leads to complementary among measurements at various neutrino sources with different targets. Latest results and prospects of observing this process at the Kuo-Sheng Reactor Neutrino Laboratory (KSNL) with germanium detectors with Ο(100 eV) threshold will also be presented.
