<正> Our calculations with phase shift analysis are carried out in three energyregions.The effective range approximations with 4 partial waves are adoptedfor the energy region of E_n<11 MeV.The parametrized p-D phase shifts areadoptable on the assumption of charge symmetry in mirror scattering for 12MeV<E_n<20 MeV and these phase shifts are adjusted to get the good agree-ment between the theoretical values of n—D scattering cross sections and exper-
