Effect of heavy ions irradiation on LiTaO3 crystal

Results in Physics, 2021
In this work, congruent LiTaO3 crystals are irradiated by heavy ions Fe, Xe, and Bi respectively at fluence range of 1 × 1012 ~ 2 × 1015 cm−2. The effects of heavy ions irradiation are studied by using optical transmission spectroscopy, Rutherford ...

Probing QED Vacuum with Heavy Ions

, 2016
We recall how nearly half a century ago the proposal was made to explore the structure of the quantum vacuum using slow heavy-ion collisions. Pursuing this topic we review the foundational concept of spontaneous vacuum decay accompanied by observable ...

Photon-Photon and Pomeron-Pomeron Processes in Peripheral Heavy Ion Collisions [PDF]

, 2000
We estimate the cross sections for the production of resonances, pion pairs and a central cluster of hadrons in peripheral heavy-ion collisions through two-photon and double-pomeron exchange, at energies that will be available at RHIC and LHC. The effect

Prospects for parity-nonconservation experiments with highly charged heavy ions [PDF]

, 2006
We discuss the prospects for parity-nonconservation experiments with highly charged heavy ions. Energy levels and parity mixing for heavy ions with 2–5 electrons are calculated.

Iron-rich solar particle events measured by SOHO/ERNE during two solar cycles

, 2016
We study the differences in the heavy ion composition of solar energetic particle (SEP) events between solar cycles 23 and 24. We have surveyed the SOHO/ERNE heavy ion data from the beginning of solar cycle 23 until the end of June 2015, that is, well ...

First observations of beam losses due to bound-free pair production in a heavy-ion collider [PDF]

, 2007
We report the first observations of beam losses due to bound-free pair production at the interaction point of a heavy-ion collider. This process is expected to be a major luminosity limit for the Large Hadron Collider (LHC) when it operates with 208Pb82+

Discriminative detection of laser-accelerated multi-MeV carbon ions utilizing solid state nuclear track detectors

Scientific Reports, 2021
A new diagnosis method for the discriminative detection of laser-accelerated multi-MeV carbon ions from background oxygen ions utilizing solid-state nuclear track detectors (SSNTDs) is proposed. The idea is to combine two kinds of SSNTDs having different
