获得了He、Ne和Ar原子弹性散射电子的高能量分辨谱，它是散射角和入射电子能量的函数。除了众所周知的暂时负离子(共振)最低组态能级外，作者还观察到了能量接近(核)Np5(n+1)S能级的Ne和Ar能级的结构。这些结构归因于具有组态(芯)NP5((n+1)S(n+1)P3P)的共振。通过对弹性散射谱和亚稳态激发谱中已知能量处出现的特征进行校准，它们准确地确定了观测到的共振的能量。
High energy-resolution spectra of electrons scattered elastically from helium, neon and argon atoms have been obtained as functions of scattering angle and of incident electron energy. In addition to the well known levels of the lowest configurations of the temporary negative ions (resonances), the authors observe structures at energies close to those of the (core)np5(n+1)s levels of neon and argon. These structures are attributed to resonances having configurations (core)np5((n+1)s(n+1)p3P). By calibration against features occurring at known energies in the elastic scattering spectra and also metastable excitation spectra they determine accurately the energies of the observed resonances.
