The Electron Impact Ionization Efficiency Curve of Zinc

Autor: Nobuhide Wasada, Akio Hashizume

Publikováno v: Japanese Journal of Applied Physics. 18:429-438

The ionization efficiency curve of Zn by electron impact has been measured from the threshold energy to 12.7 eV. An energy resolution of 0.05 eV has been obtained by applying an inverse convolution method. Many structures due to autoionization have b

Electron-impact ionization efficiency curves of Kr and Xe near the ionization threshold

Autor: Nobuhide Wasada, Akio Hashizume

Publikováno v: International Journal of Mass Spectrometry and Ion Physics. 36:291-299

The electron-impact ionization efficiency curves of Kr and Xe near the ionization threshold of the respective atoms are measured by Vogt's method. The energies of the structures found in the first derivative of the ionization efficiency curves are co

An Integrated Spectral Data Base System Including IR, MS, 1H-NMR, 13C-NMR, ESR and Raman Spectra

Autor: Jiro Hiraishi, Tadao Tamura, Kazuo Someno, Nobuhide Wasada, Osamu Yamamoto, Masaru Yanagisawa, Kikuko Hayamizu, Kazutoshi Tanabe

Publikováno v: Analytical Sciences. 4:233-239

An integrated spectral data base system named SDBS was constructed, in which six kinds of spectral data, i.e., data of IR, MS, 1H-NMR, 13C-NMR, ESR and Raman spectra were compiled in an integrated way under the control of a directory data base. The s

An Application and Modification of the Freeze-out Technique by Quiram and Biller for the Determination of Pollutants in the Atmosphere by Mass Spectrometry

Autor: Nobuhide Wasada, Toshikazu Tsuchiya, Hiroko Hoshino

Publikováno v: Bulletin of the Chemical Society of Japan. 37:1310-1313

Quiram and Biller’s freeze-out method, originally devised to determine hydrocarbons contained in air above l0 p.p.m. and using a mass spectrometer, was tried on a trace (down to 1/100 p.p.m.) of mercury vapor in atmosphere ; it was proved to give s
