一种新的技术已经开发出来，采用局部扰动的径向核光学势，它允许直接调查的灵敏度的弹性散射数据的光学模型分析的径向潜力的细节。据发现，轻和重离子散射探针主要是核表面区域。较高能量的散射数据比较低能量的数据更深入地探测到内部。原子核中心的电势值无法确定，只能在指定固定参数化（如Woods-Saxon几何）的情况下进行推断。此外，还发现虚势的径向灵敏度区域比真实的势的径向灵敏度区域系统地更靠近核的中心。
A new technique has been developed, employing a localized perturbation of the radial nuclear optical potential, which permits direct investigation of the sensitivities of optical model analysis of elastic scattering data to the details of the radial potential. It is found that both light- and heavy-ion scattering probe primarily the nuclear surface region. Higher energy scattering data probe further into the interior than lower energy data. The value of the potential at the center of the nucleus cannot be determined, but only inferred if a fixed parametrization such as Woods-Saxon geometry is specified. In addition, it is found that the region of radial sensitivity of the imaginary potential is systematically closer to the center of the nucleus than is that of the real potential.
