The quasi-elastic scattering (QES) process has been studied for the (p, n) reaction at 300 and 400 MeV. Energy spectra for targets ranging from ^{2}H to ^{nat}Pb have been obtained for a wide range of scattering angles corresponding to momentum transfers q = 1.0 - 2.4 fm^{-1}. Energy shift of the QES peak from that of ^{2}H to higher excitation energy is observed for all targets studied, with a gradual increase with target mass reaching almost a constant value of ∼26 MeV beyond ^{12}C. The mass dependence oo the effective neutron number (N_{eff}) for the (p, n) QFS process is well represented by N_{eff} = 0.85N^{0.5} over a wide mass range from ^{2}H to ^{nat}Pb except for ^{6}Li, ^{7}Li and ^{9}Be which deviate significantly. The analyzing powers of the QES peak region for the ^{12}C and ^{40}Ca targets are compared to those of the ^{2}H(p, n) reaction at 300 and 400 MeV and found to be almost identical for q ≤ 1.5 fm^{-1}. Transverse polarization transfer coefficients at 0 degree D_{NN}(0°) have been measured for the 1p shell nuclei at 300 MeV. Large negative D_{NN}(0°) values are observed for the continuum region up to an excitation energy of 50 MeV irrespective of targets. The D_{NN}(0°) values observed for the GT transitions are around -0.28 which indicates the contribution from the tensor interactions. The DWIA calculations well reproduce the observed D_{NN}(0°) values.
