Abstract:We have studied the explosion dynamics of methane clusters irradiated by intense, femtosecond, 38 nm (32.6 eV) XUV laser pulses. The ion time-of-flight spectrum measured with a Wiley-McLarentype time-of-flight spectrometer reveals undissociated molecular CH + 4 ions, fragments which are missing hydrogen atoms due to the breakage of one or more C-H bonds (CH + 3 , CH + 2 and CH + ) and the recombination product CH + 5 . Also visible on the time-of-flight traces are atomic and molecular hydrogen ions (H + and H … Show more
