“…The outstanding integrity of its polycrystalline, manufactured through a traditional ceramic processing route, is of particular importance in developing IMF for transmuting transuranium elements [3]. For the implantation of Au ions, we can estimate its deposition profile using the classic SRIM [18] with an average threshold displacement energy (Ed) of 40 eV for both zirconium (Zr) and nitrogen (N) atoms [12,19]. Without considering the thermal effect, the predicted damage region should be inside about 0.5 μm.…”

We report an as-hot-pressed zirconium nitride polycrystalline with its primary crystal structure maintained no change but lattice defects and features were introduced at nanometre-scale after being irradiated by 4 MeV Au 2+ with a total fluence of 5x10 16 /cm 2. The variation of grey-level seen in backscattered electron images and electron backscattered diffraction maps directly evidenced the structure integrity of the polycrystalline ZrN is well maintained with no crystal structure change of ZrN. The irradiation depth had no relevance to crystal orientation, and Au deposition peaked at a depth of ~0.58 μm with a near-Gaussian distribution. Within a depth <0.58 μm, long dislocation lines were developed with a Burgers vector of [011 ]b/2 and density 3.2x10 14 1/m 2 ; beyond this depth, dislocation loops were formed with much higher density. In the ionization zone, cubic ZrO2 crystallites precipitated in a size of ~5 nm. The irradiation damage processes are discussed based on the observed features.

“…SRIM is fairly good everywhere, except near the maximum (2.5 -30 MeV/n). By detailed analysis, it can be shown, that on the average, for heavy ions in solid elemental targets, SRIM is 6 % high in heavy targets and 5 % low in light targets at the maximum, as has been noted already by Randhawa & Virk (1996). For examples, see the graphs for U in Au (Fig.…”

“…As a consequence of the different collision frequencies in solids and gases the ionization of the heavy ions should be larger inside solids. There are reports [4][5][6][7][8][9][10], which indicate that the experimental range and stopping power values for heavy ions deviate significantly, from the often used formulations [3,[11][12][13][14]. A number of promising theoretical and semi-empirical approaches are available at present.…”

A comparative study of various stopping power tables and codes for heavy ions in gases has been made through comparison of computed values and the corresponding experimental data. Ten gaseous media : five monatomic rare gases (He to Xe), two diatomic gases (H 2 , N 2 ) and three polyatomic gaseous compounds (CH 4 , CF 4 and CO 2 ) have been chosen to study the stopping power investigations of heavy ions (8 £ Z £ 92) having energy ranges of ~0.10-10.00 MeV/n and ~20.00-57.00 MeV/n. We compare the experimental data of stopping power to values calculated using various tables and computer codes by ICRU-73, Ziegler et al (SRIM2003.26), Grande and Schiwietz (CasP3.1), Paul and Schinner (MSTAR3.12), and Bazin and Tarasov (LISE ++:2-ATIMA1.2). On the basis of statistical analysis, we estimate the reliability of these tables and codes. It has been observed that the MSTAR3.12 code shows the best agreement with the experimental data for projectile ions (8 £ Z £ 18) in the entire energy range. The SRIM2003.26 code provides good results except for some heavy projectiles (Xe, Pb and U). The values tabulated by CasP3.1 code underestimate especially at low energy region. No significant trend is observed in case of LISE++:2-ATIMA1.2 code and ICRU-73 report.
