The stopping cross-sections of N2, H2, CH4, C4H10 and C3H6 have been measured using natural alpha particles from a 238Pu source, with facilities to vary the energy in the range 1.3--4.2 MeV. The work is the extension of measurements made earlier, using C2H4 as the absorber, which showed discrepancies in comparison with results of other authors. The comparison is continued with the results presented here and brief comments made on the degree of agreement obtained.
利用来自238Pu源的天然α粒子，在能量范围为1.3 - 4.2 MeV可变的条件下，测量了N2、H2、CH4、C4H10和C3H6的阻止截面。这项工作是早期以C2H4为吸收体进行测量的扩展，早期测量结果与其他作者的结果相比存在差异。本文继续将测量结果进行比较，并对所获得的一致程度作简要评论。
