本文报道了1994年11月至1998年4月期间太阳和行星际宁静期内原子序数Z在2≤Z≤36范围内、能量约为3-20 MeV amu-1的离子的能谱和丰度。能谱显示星系和“异常”宇宙射线成分（分别为GCR和ACR）的存在，取决于元素。ACR组件的Mg和Si的首次报告在1 Au，并证实了以前的观察S和Ar。然而，对于元素Ca、Ti、Cr、Fe以及对于C，仅GCR分量是清楚地明显的。对其他元素（包括Kr）可能的ACR贡献设置了新的限制。
We report the energy spectra and abundances of ions with atomic number, Z, in the interval 2≤Z≤36 and energies ~3-20 MeV amu-1 for solar and interplanetary quiet periods between 1994 November and 1998 April, as measured by the large-geometry Low-Energy Matrix Telescope on the Wind spacecraft near Earth. The energy spectra show the presence of galactic and "anomalous" cosmic-ray components (GCR and ACR, respectively), depending on the element. ACR components are reported for Mg and Si for the first time at 1 AU, and the previous observation of S and Ar is confirmed. However, only GCR components are clearly apparent for the elements Ca, Ti, Cr, Fe, as well as for C. New limits are placed on a possible ACR contribution for other elements, including Kr.
