中文摘要：

用相对论脉冲近似（RIA）对不同的中能质子（200MeV，400MeV和800MeV）与MBe，^16O和^12C的弹性散射进行了研究，讨论了不同的入射能量对3种观测量，即微分散射截面、分析本领和自旋转动函数的影响，研究发现在小散射角的区域晕中子对观察量的影响趋势保持一致，不随入射质子能量的改变而改变。

英文摘要：

The proton elastic scatterings on ^14Be, ^16O and ^12C at the intermediate incident energies of 200, 400 and 800MeV, are investigated within the relativistic impulse approximation （RIA）. The effect of the incident energy on three observables, the differential cross section, the analyzing power and the spin rotation function, is discussed. It is shown that in the region of small scattering angle, the halo neutron effect on the observables exhibits an unchanged tendency with the variation of the incident energy of proton in the intermediate energy region.
