| 英文摘要 | We experimentally explore weak space charge effects (SCEs) in multiphoton ionization (MPI) experiments using C-60 as an example of heavy species. The laser-induced delayed ionization of C-60 was used to prepare a photoion pulse with a decreasing initial charge density distribution from a start value that is one order of magnitude smaller than the density limit (3x10(8) ions/cm(3)) proposed previously to assume that the SCEs can be negligible. The photoion spectra at different time slices of the photoion pulse were measured using a velocity map imaging spectrometry. This allows us to quantify the SCEs on the photoion spectrain such low-density and heavy-species regime. The weak SCEs explored here can help us to understand and improve the temporal-spatial resolutions in those high-precision measurements. (C) 2019 Elsevier B.V. All rights reserved. |
