Resonance States of Negative Hydrogen-like Ions in Quantum Plasmas
Atoms, 2023 We studied the 1Se and 1,3Po resonance states of negative hydrogen-like ions immersed in quantum plasmas. The exponential cosine screened Coulomb potential was considered to model the quantum plasma environment.

Fragmentation of metal(II) bis(acetylacetonate) complexes induced by slow electrons
Beilstein Journal of Nanotechnology, 2023 Nowadays, organometallic complexes receive particular attention because of their use in the design of pure nanoscale metal structures. In the present work, we present results obtained from a series of studies on the degradation of metal(II) bis ...

Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1936 In a previous paper we have applied quantum-theoretical considerations to the passage of positive ions through gases, but in certain circumstances, as for example the electric discharge in iodine vapour, negative ions are of importance. Very little has been done in discussing theoretically the behaviour of such ions, and in fact there has ...

New Journal of Physics, 2017 Negative ion sources for fusion are high densities plasma sources in large discharge volumes. There are many challenges in the modeling of these sources, due to numerical constraints associated with the high plasma density, to the coupling between plasma

Existence of ground states for negative ions at the binding threshold [PDF]
, 2013 As the nuclear charge Z is continuously decreased an N-electron atom undergoes a binding-unbinding transition at some critical Z_c. We investigate whether the electrons remain bound when Z=Z_c and whether the radius of the system stays finite as Z_c is ...

Diagnostics tools and methods for negative ion source plasmas, a review
New Journal of Physics, 2017 Plasma parameter measurements for negative hydrogen (H ^− ) ion sources have been playing an important role in clarifying fundamental physics related to negative ion production and destruction processes. Measured data of beam properties, such as H ^− ion

Coulomb implosion mechanism of negative ion acceleration in laser plasmas
, 2008 Coulomb implosion mechanism of the negatively charged ion acceleration in laser plasmas is proposed. When a cluster target is irradiated by an intense laser pulse and the Coulomb explosion of positively charged ions occurs, the negative ions are ...
