Charge-state dependence of nuclear lifetimes

Physical Review Letters, 1989
Measurements of conversion rates are reported for the first time in one- and two-electron systems, for the 14.4-keV nuclear state in $^{57}\mathrm{Fe}$. The total half-life of this state deduced for the two-electron ion is 100\ifmmode\pm\else\textpm\fi{}5 ns, and that deduced for the total spin F=1 state of the one-electron ion is 79\ifmmode\pm\else ...

State of charge

IEEE Spectrum, 2012
In a cloud of car exhaust during a Friday rush hour, I'm humming over San Francisco's Golden Gate Bridge in an all-electric, tailpipe-free Nissan Leaf. I've plotted a course for Vacaville, 88 kilometers (55 miles) north, known for its sprawling outlet mall.

Formation of different charge states and the charge state fractions of sputtered Ti and Ni

Surface Science Letters, 1986
Abstract The energy and angular dependences of the charge state fraction η i of Ti and Ni particles sputtered in binary collisions with Ne + and Ar + ions were determined. It was found that the charge states strongly depend on v ⊥ , the velocity component normal to the surface, and on the species of the primary ions. Monte Carlo simulations (

BATTERIES | Adaptive State-of-Charge Determination

2009
This article gives an overview of available state-of-charge (SoC)-indication methodologies and highlights many related practical implementation issues. First of all, a brief history of the developments in SoC indication is given. The lithium-ion battery technology is briefly discussed as illustration, because battery behavior needs to be understood and

Battery state-of-charge estimation

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
This paper discusses the problem of lead acid battery state-of-charge estimation for (hybrid) electric vehicles. The problem is to accurately estimate the remaining battery capacity for both driver notification and automated energy management. The article presents a review of the problem, existing solution methods, presentation of a new solution method,

Charged states of thiophene oligomers

International Conference on Science and Technology of Synthetic Metals, 1994
Summary form only given. Optical chemical doping and photoexcitation studies of thiophene oligomers were carried out. We observed a number of broad charge-induced infrared active vibrational modes and two associated electronic absorption peaks suggesting bipolaron formation durring chemical doping and photoexcitation.

Theory of charge states in sputtering

Nuclear Instruments and Methods in Physics Research, 1981
The ionization of particles sputtered from solid state substrates is a complex phenomenon which involves motions and strong electronic perturbations of a large number of atoms and may comprise several independent physical processes. Thus, a theoretical description of charge states of sputtered particles which would be more than a working hypothesis ...

Gap states of charged solitons in polyacetylene

Physical Review B, 1989
Abstract : By considering the electron interactions in polyacetylene, it is found that there exist two gap states in charged solitons of trans- polyacetylene: one is deep level, and the other is shallow level. The deep one shifts 0.23 eV down (for a positive soliton) or up (for a negative soliton) from the center of the gap, while the shallow one is 0 ...

State of charge estimator for NiMH batteries

Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003
A state of charge estimator for Nickel-Metal Hydride batteries, suitable for hybrid vehicles automotive applications, is proposed. The estimator is based on a statespace dynamic model of the battery which is obtained by modeling the kinetic of reactions and the diffusion phenomena.
