电子在GeHA分子上的绝对总散射截面在15-40CU eV之间被测量。总截面对能量的依赖关系与较轻的氢化物、CH和SiHA不同。已经注意到，在高能极限下，氢化物的总截面趋向于相应的等电子惰性气体的值。检验了不同的实验部分截面与绝对总截面之间的自洽性。为这些气体设定了解离成中性碎片的上限。通过对用这种方法选择的部分截面的比较，得出了稀有气体和类稀有分子(CHa，Sihn)不同分配方案的结论。GeH4已绘制。在中能区，非弹性过程主导着电子在分子上的散射。在IOOeV，CHI-Ne对的弹性截面几乎相等。西哈尔。GeH4-Kr.
Absolute total cross sections for electron scattering on GeHa molecules have been measured between 15 and 40CU eV. The dependence of the total cross section on energy is revealed to be different than for the lighter hydrides, CH, and SiHa. It has been noticed that in the high energy limit the total cross sections for hydrides tend to die values of the corresponding isoeledronic noble gases. Self-consistency between diferent experimental partial cross sections and the absolute total cross section is checked for CHI, SiHn and GeH,. Upper limits for dissociation into neutral fragments are set for these gases. By comparison of the partial cross sections selected in this way, a conclusion on different partitioning schemes for noble gases and noble-like molecules (CHa, SiHn. GeH4 is drawn. At intermediate energies the inelastic processes dominate the electron scattering on molecules. At IOOeV the elastic cross sections are almost equal for the pairs CHI-Ne. SiHa-Ar. GeH4-Kr.
