Journal of Applied Physics, 2021 In this Tutorial, surface and double charge exchange negative ion sources for producing negative ion beams of different ion species will be described. The need for negative ions as the beam particles of tandem Van de Graaf accelerators and that for charge exchange injection of hydrogen negative ions into high-energy proton accelerators requires the ...

Ion-Pair Formation in Neutral Potassium-Neutral Pyrimidine Collisions: Electron Transfer Experiments
Frontiers in Chemistry, 2019 We report novel data on ion-pair formation in hyperthermal (30–800 eV) neutral potassium collisions with neutral pyrimidine (Pyr, C4H4N2) molecules. In this collision regime, negative ions formed by electron transfer from the alkali atom to the target ...

Formation of p-, n-conductivity in semiconductors / Формирование p-, n-проводимости в полупроводниках / Formiranje provodljivosti kod poluprovodnika P-tipa i N-tipa [PDF]
Vojnotehnički Glasnik, 2018 The paper considers the energy position of negative ions of impurity atoms in the band gap of a semiconductor. Owing to the Boltzmann law, the energy levels of negative ions in the vicinity of the conduction band supply electrons to the conduction ...

Multiphoton detachment of electrons from negative ions [PDF]
, 1997 A simple analytical solution for the problem of multiphoton detachment from negative ions by a linearly polarized laser field is found. It is valid in the wide range of intensities and frequencies of the field, from the perturbation theory to the ...

Negative ions and their role in the development of science and technology / Отрицательные ионы и их роль в развитии науки и технологии / Negativni joni i njihova uloga u razvoju nauke i tehnologije [PDF]
Vojnotehnički Glasnik, 2018 Negative ions are formed in the process of the interaction between the electron with the integrated electric dipole moment and the induced electric dipole moment due to polarization.

Retrieval of electron-atom scattering cross sections from laser-induced electron rescattering of atomic negative ions in intense laser fields [PDF]
, 2007 We investigated the two-dimensional electron momentum distributions of atomic negative ions in an intense laser field by solving the time-dependent Schrodinger equation (TDSE) and using the first- and 2nd-order strong-field approximations (SFA).
