“…Before the SCA formalism is discussed binding energies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and fluorescence yields [20] of the Nsubshells are collected in Table 1. From the binding energies it is excluded that a ionization of the N(VI, VII)-subshell is responsible for a roughly 210eV radiation.…”

We present here detailed simulations of the interaction of energetic C 10 and C 5 clusters at the energies of 1, 2, and 4 MeV per carbon atom with an amorphous carbon target. The spatial evolution of the cluster components is simulated accounting for both scattering and Coulomb explosion. The former is calculated by means of the Monte Carlo method while the latter is computed by means of molecular dynamics. The charge state of the individual cluster components is calculated as a function of penetration depth, and is determined by the competition between electron ionization and recombination. The results of calculations of the effect of the neighbouring cluster components on the suppression of the values of the charge state are presented and compared to the experimental values of Brunelle et al. Charge state suppression calculations for the 2 MeV/C clusters for both C 10 and C 5 agree well with the experimental results for penetration depths of less than about 500 and 250Å respectively, assuming the intracluster Coulomb potential is screened by four target valence electrons. At 4 MeV/C the results are similar although less screening is required; a possible explanation is the inability of the plasma to completely screen the higher velocity projectiles. The 1 MeV/C calculated results however differ in their behaviour from the 2 and 4 MeV/C cases.

“…This d1str1.but1on has been observed in satellite K x-ray spectra (simultaneous K-and L-vacancy production) [3], hypersatellite spectra (simultaneous double K-vacancy production) [4], in multiple-ionization and multiple capture [5,7], and in recoil ion measurements [8,9]. To date, detailed comparisons between calculated and measured multiple-ionization or excitation cross sections have been hampered by various side effects.…”
