Large increase in the electron capture and excitation cross sections for Li+ colliding with atomic H under UV laser assistance

摘要: Neutralization and ash products due to electron capture processes in plasmas reduce the efficiency of energy generation fusion Tokamak reactors. Therefore, lithium ions have been used improve where good control process is required. Here, we show that an intense ( W cm−2), ultra-short (1 fs at full width half-maximum) Gaussian laser pulse UV region can enhance on low collision keV region. We find a factor 10 enhancement cross-section impact energies lower than amu−1 for 80 nm wavelength 2 excitation hydrogen atom as compared laser-free case. In contrast, 200 increase cross-sections takes place around 1 by 3 no process. Our results assisted production Li be controlled, particularly short wave-length specific range. anticipate our findings will facilitate reactors encourage further experimental work this system.
