Comparison of IMFPs for water calculated from optical data by Emfietzoglou et al. with our IMFPs from the FPA (solid line, Table 1), the SPA (long- and short-dashed line), SSPA (long-dashed line), EM (short-dashed line) and the SSPA* (dotted line) models for energies between 10 eV and 10 keV. (a) The solid circles, squares, triangles show the IMFPs of Emfietzoglou et al. published in 2002 [9], 2005 [10], and 2007 [11], respectively. (b) The solid triangles and downwards triangles show the IMFPs of Emfietzoglou et al. published in 2012 [12] and 2013 [13], respectively.
