论文摘要
jovian磁层内的硫离子的普及导致了这些离子将这些离子植入欧罗巴表面的建议可能导致SO2的形成。然而，先前关于将硫离子植入H2O冰的研究（欧洲表面上的主要物种）未能检测到SO2的形成。与欧罗巴存在相似的二氧化碳冰植入有关的其他研究也提供了似乎相互矛盾的结果。在这封信中，我们描述了一项关于在20和70 K处植入290 keV s+离子中的二氧化碳中的研究结果。我们的结果表明，在20 K处植入后植入后观察到SO2，但不能在欧罗巴岛相关的温度为70 K的温度下，但在70 k的温度下，我们可能不应该结论一下SO2的合理机制，而不是SO2上的Europa，以及其他机构，以及其他机制，以及其他机制。
The ubiquity of sulfur ions within the Jovian magnetosphere has led to suggestions that the implantation of these ions into the surface of Europa may lead to the formation of SO2. However, previous studies on the implantation of sulfur ions into H2O ice (the dominant species on the Europan surface) have failed to detect SO2 formation. Other studies concerned with similar implantations into CO2 ice, which is also known to exist on Europa, have offered seemingly conflicting results. In this letter, we describe the results of a study on the implantation of 290 keV S+ ions into condensed CO2 at 20 and 70 K. Our results demonstrate that SO2 is observed after implantation at 20 K, but not at the Europa-relevant temperature of 70 K. We conclude that this process is likely not a reasonable mechanism for SO2 formation on Europa, and that other mechanisms should be explored instead.
