Swift heavy ion tracks in SiTiO3 [PDF]

, 2012
Međudjelovanje energetskog teškog iona s materijom može rezultirati dramatičnim promjenama materijala, što čini ozračavanja pojedinačnim ionima jedinstvenim oruđem za modifikacije na nanoskali. Potrebne ekstremne gustoće energije mogu biti postignute koristeći samo brze teške ione (swift heavy ions, SHI) ili ione visokog nabojnog stanja (highly charged

Local formation of nitrogen-vacancy centers in diamond by swift heavy ions [PDF]

, 2014
We exposed nitrogen-implanted diamonds to beams of swift heavy ions (∼1 GeV, ∼4 MeV/u) and find that these irradiations lead directly to the formation of nitrogen vacancy (NV) centers, without thermal annealing.

Irradiation Effects of Swift Heavy Ions Detected by Refractive Index Depth Profiling

Quantum Beam Science, 2020
Evolution of depth profiles of the refractive index in Y3Al5O12 (YAG) crystals were studied under 200 MeV 136Xe14+ ion irradiation, since the index can be related with the stress change and/or the defect formation by the irradiation.

The Effect of Fast Kr Ion Irradiation on the Optical Absorption, Luminescence, and Raman Spectra of BaFBr Crystals

Crystals, 2023
In this work, using photoluminescence (PL), optical absorption (OA), Raman spectroscopy (RS), and atomic force microscopy (AFM), the radiation damage of BaFBr crystals irradiated with 147 MeV 84Kr ions to fluences (1010–1014) cm2 was investigated.

Density changes in amorphous silicon induced by swift heavy ions

, 2022
Pure and gold-doped amorphous silicon membranes were irradiated with swift heavy ions (75 MeV Ag or 1.1 GeV Au ions) and studied using small-angle x-ray scattering.

Swift Heavy Ion-induced Mixing

Defence Science Journal, 2009
In this paper, the possible swift heavy ion (SHI)-matter interaction processes and their applicability to SHI-induced mixing have been discussed. The assumption that the SHI mixing is a consequence of a transient molten state diffusion has been brought forward.
