The process by which a molecule in an intense laser field ionizes more efficiently as its bond length increases towards critical distance ${R}_{c}$ is known charge resonance enhanced ionization (CREI). We make series of measurements this for ${\mathrm{CO}}_{2}$, varying pulse duration from 7 to 200 fs, order identify the states and time scales involved. find that $4+$ higher states, 100 fs scale required reach geometry $⟨{R}_{\mathrm{CO}}⟩\ensuremath{\approx}2.1\text{ }\text{ }\AA{}$...
We have measured full momentum images of electrons rescattered from Xe, Kr, and Ar following the liberation these atoms by short, intense laser pulses. At high momenta spectra show angular structure (diffraction) which is very target dependent in good agreement with calculated differential cross sections for scattering free corresponding ionic cores.
Secondary electrons play critical roles in several imaging technologies, including extreme ultraviolet (EUV) lithography. At longer wavelengths of light (e.g. 193 and 248 nm), the photons are directly involved photochemistry occurring during photolysis. EUV (13.5 nm, 92 eV), however, first creates a photoelectron, this electron, or its subsequent daughter create most chemical changes that occur exposure. Despite importance these electrons, details surrounding events leading to acid...
Attosecond science has opened up the possibility of manipulating electrons on their fundamental timescales. Here, we use both theory and experiment to investigate ionization dynamics in helium attosecond timescale by simultaneously irradiating atom with a soft x-ray pulse train (APT) an ultrafast laser pulse. Because APT resolution energy time, observe processes that could not be observed without domains simultaneously. We show resonant absorption is important excitation small changes...
We demonstrate a method for determining the full three-dimensional molecular-frame photoelectron angular distribution in polyatomic molecules using methane as prototype. Simultaneous double Auger decay and subsequent dissociation allow measurement of initial momentum vectors ionic fragments coincidence, allowing orientation by observing three-ion pathway, (H+, H+, CH2(+)). find striking result that at low energies molecule is effectively imaged focusing photoelectrons along bond directions.

We present experimental measurements and theoretical calculations for the photoionization of CH4 at carbon K-edge. Measurements performed using cold target recoil ion momentum spectroscopy (COLTRIMS) combined with complex Kohn variational photoelectron in molecular frame demonstrate surprising result that low energy photoelectrons effectively image molecule by emerging along bond axes. Furthermore, we observe a dynamic breakdown axial behaviour one dissociation pathways intermediate...
We employed electron-ion coincidence momentum spectroscopy to measure the relative angle between an emitted electron and a deuteron resulting from field dissociation of molecular ion produced by circularly polarized pulse. deduced angular dependence ionization probability without having align molecules first. determined that with 50 fs pulses 1850 nm wavelength $2\ifmmode\times\else\texttimes\fi{}{10}^{14}\text{ }\text{W}/{\text{cm}}^{2}$ intensity neutral ${\text{D}}_{2}$ are 1.15 times...
We have used cold target recoil ion momentum spectroscopy to study the continuum correlation between photoelectron of core-photoionized neon and subsequent Auger electron. observe a strong angular two electrons. Classical trajectory Monte Carlo calculations agree quite well with energy distribution that is shifted due potential change associated decay. However, striking discrepancy results in relative angle photoelectron. The classical model predicts shift flux away from emission direction,...

Particular attention is paid to preventive resolution as least controversial, allowing reducing or eliminating possibility a conflict within labor sphere, fair effective method that reduces burden on civil courts conditions limited budget spending. It advisable give priority out-of-court methods for disputes, direct efforts prevent emergence conflicts. Implementation this strategy should be...

The principal–agent problem attracted attention from researchers 20 years ago in connection with Enron. paper reports on the behavioral experiment of designing energy executive compensation contracts. An experimental approach based theory was applied (1) to design a fixed and variable component contract, (2) assess impact information disclosure terms (3) estimate response manager's efforts contract. Hypotheses testing showed that (a) does not affect decision-making owners (principals)...
