摘 要:The measurement of parity-violating (PV) observables in few-nucleon system can shed light on our current understanding of the weak interaction between *** models describe the nucleonnucleon weak interaction at low energies use a series of undetermined *** parity violating measurements have been considered: the capture of polarized slow neutrons on hydrogen (n + p → d + γ) at Los Alamos National Laboratory for first phase and Oka Ridge National Laboratory for second phase and the helicity dependence of the deuteron photodisintegration cross section using circularly polarized photons (γ + d → n + p) at Shanghai Institute of Applied *** goal of both experiments is to constraint the weak meson-nucleon couplings to a precision of 1 ×10^-8 .The introduction of both experiments is presented.
