摘要: A double‐focusing mass spectrometer in conjunction with a cluster beam source has been used to study the unimolecular fragmentation patterns of krypton ions, Kr+n, for n range 10–340. All ions are observed undergo reaction Kr+n →Kr+n−1 + Kr; however, some clusters lose up five atoms on time scale experiment. The six naturally occurring isotopes complicates cluster‐ion spectra, number ion peaks increasing rapidly given Kr+n. computer model which successfully accounts influence reveals that isotope enrichment occurs. relative intensities fragment exhibits pronounced intensity fluctuations, many coincide similar observations large argon ions. It is proposed particularly intense fragments, i.e., Kr+111 and Kr+120, arise from reactions lead formation kinetically favorable products. In contrast, m...
