  1. The crossover (E0) and the bulk plasmon energies (Ep) are expressed in eV. The effective EELS intensity coefficient (h) is calculated at E = E0 and expressed in arbitrary units. PHECs are ordered in four Classes depending on the the number of composing TMs from group 4 g4 (Ti, Nb, Hf), group 5 g5 (V, Nb, Ta), and group 6 g6 (Cr, Mo, W) of the periodic table.
