    "abstract": "The preequilibrium (nucleon-in, nucleon-out) angular distributions of\n$^{27}$Al, $^{58}$Ni and $^{90}$Zr have been analyzed in the energy region from\n90 to 200 MeV in terms of the Quantum Moleculear Dynamics (QMD) theory. First,\nwe show that the present approach can reproduce the measured (p,xp\u0027) and (p,xn)\nangular distributions leading to continuous final states without adjusing any\nparameters. Second, we show the results of the detailed study of the\npreequilibrium reaction processes; the step-wise contribution to the angular\ndistribution, comparison with the quantum-mechanical Feshbach-Kerman-Koonin\ntheory, the effects of momentum distribution and surface refraction/reflection\nto the quasifree scattering. Finally, the present method was used to assess the\nimportance of multiple preequilibrium particle emission as a function of\nprojectile energy up to 1 GeV.",
