A Monte Carlo code to calculate transmission efficiency of HIRA

Simulation of angular and energy distributions for heavy evaporation residues using statistical model approximations and TRIM code

“…We examined SRIM suitability for Table 1 ER data on the projectile-target combinations mentioned in Refs. [1][2][3][4][5][9][10][11][12]14,16,25] and HI data [28,31,32] on transmission through the targets of a different thickness.…”

“…The data listed in Table 1 for ERs produced in the projectile-target combinations mentioned in Refs. [1][2][3][4][5][9][10][11][12][13][14]16,25] are shown by open triangles. The HI data derived from the simulated angular distributions (open symbols) and from measurements (full symbols) for 238 U passed through the Bi target [28], for 20 Ne, 209 Bi [31] and 40 Ar [32] passed through thin carbon foils, are also shown (see Table 1 and the text for details).…”

“…The TERS code [14], developed to calculate the transmission efficiency of the HIRA recoil separator, treats light-particles evaporation in great detail, whereas the treatment of MS is questionable. For the latter, the author [14] used the approximations [15] applicable for the transmission of relativistic particles through matter, which do not take into account the Coulomb screening of interacting atoms (see, for example [7]). Since the applicability of the approximations [15] was not discussed and no comparison of simulations with experimental data was provided, the angular distributions presented in Ref.…”

“…Since the applicability of the approximations [15] was not discussed and no comparison of simulations with experimental data was provided, the angular distributions presented in Ref. [14] might be questionable.…”

“…These distributions could be compared with the measured ones available from the literature to appreciate the validity of such simulations. However, one should mention that in this approach [16], as well as in those considered above [3][4][5][11][12][13][14], no comparisons of the simulated distributions with measured ones are presented.…”
