质子从/sup 12/C的弹性散射数据进行了唯象分析，通过使用本地的，复杂的，单通道的光学模型的潜力，并在一个扩展的耦合反应通道环境。虽然从拾取剥离路径通过/sup 11/C中间状态的弹性通道中的背耦合振幅被发现是相当大的，光学模型势是能够模拟的散射和反应过程中的能量大于约60兆电子伏的效果相当不错。发现耦合反应通道环境的光学模型势和剩余光学模型势的参数随能量平滑地变化。低于60 MeV，这些参数有很大不同的趋势和能力的单通道光学模型潜力，以模拟强耦合的奇异效应大大降低。
Elastic scattering data for proton scattering from /sup 12/C are analyzed phenomenologically by use of local, complex, one-channel optical-model potentials and in an extended coupled-reaction-channel environment. Although the back-coupling amplitudes in the elastic channel from pickup-stripping paths through /sup 11/C intermediate states are found to be quite sizable, the optical-model potential is able to simulate most of the effects quite well for both scattering and reaction processes at energies greater than about 60 MeV. The parameters of the optical-model potential and the residual optical-model potential of the coupled-reaction-channel environment are found to vary smoothly with energy. Below 60 MeV, these parameters have quite different trends and the ability of the one-channel optical-model potential to simulate the singular effects of strong couplings is much reduced.
