Abstract
H2O:C2H6 ice mixture, in a proportion of approximately 1:10 and at 60 K in average, is irradiated by energetic multicharged ions (≈65MeV252Cf fission fragments). The sputtered positive and negative secondary ions are analyzed by time-of-flight plasma desorption mass spectrometry (PDMS-TOF). Several ionic species are identified, indicating strong surface fragmentation and clusterization. The bombardment induces the formation of the ion cluster series: (CH2)nX, where X = CH3+, C2H6+ or CH+, and the carbon cluster series (C)nX, where X = CH3+ or CH−. It is found that, in general, the yield distributions exhibit exponential decays, Y=Y0Fexp(−kFn)+Y0Sexp(−kSn), where kF=1.11 u−1 and kS=0.11 u−1. Such finding may be useful to understand the processes by which, in cosmic space, ionized molecular species of hydrocarbons are delivery to the gas phase.
