ArgonIonizationGeometrySpectroscopyQuantum Defect (QD) information is widely exploited in modern spectroscopy, tocharacterize Rydberg states and in the calculation of the photoionization cross sections of various atomic and molecular species. In the present work, we show that QD information, used within ...
We use high-resolution "zero kinetic energy photoelectron spectroscopy (ZEKE PES)" with two-colour two-photon resonant ionization for the investigation of the benzene-argon van der Waals complex in a supersonic skimmed jet. The ZEKE PE spectrum shows only a single peak of ≈8 cm 1 fwhm. We...
A direct current electric arc has been developed as a heating device for argon gas. Negligible amounts of electrode material are consumed during an operating time of several minutes. Under normal operating conditions 50% to 90% of the input electric power is transferred directly to the gas. The...
Of the following which element has the highest first ionization energy? Choose the element with the higher first ionization energy: P or Sn. Which atom has the highest ionization energy? a. Na b. P c. Cl d. K Does argon or krypton have a higher boiling point? Explain why. ...
Of the following which has the highest first ionization energy? Argon Neon Helium Krypton What is the electron configuration for boron? What is the general trend in ionization energy as you move down a column in the periodic table? What is an electron configuration of neptunium?
Experimental data, as a function of projectile energy loss, are presented for single, double and triple ionization of argon by 750eV positrons. These differential ionization yields are for positrons scattered into a forward cone of angles between 0掳 and 17掳 and for energy losses up to 85%...
Ionization cross sections, differential in the energy of secondary electrons, are presented for high-energy electrons incident on helium, neon, and argon. ... John,H.,Miller,... - 《Physical Review A》 被引量: 31发表: 1984年 Formation and decay kinetics of the 2p levels of neon, argon,...
摘要: The total ionization cross section of Ar atoms by metastable He atoms determined over the energy range 13–1500 eV by collecting slow ions measured with a quadrupolar mass analyser, is compared with existing experimental and theoretical results....
where Ii is the ionization potential, <Iex> is the average energy of atom excitation, <Nex> is the average number of excited atoms, <Ni> is the average number of electron-ion pairs, Ki is a factor taking into account multiple acts of ionization, and <E> is the average kinetic energy ...
