In this study the authors examine the reliability and validity of the Fear of Intimacy with Helping Professionals Scale (FIS-HP) with Chinese (N = 150) and American (N = 145) elderly persons. Factor analysis using principal component analysis with a varimax rotation was used to examine the FIS-HP factor structure for both samples. A three factor solution(More)
The binding energy spectra of cyclopropane in energy range of 9-19 eV have been measured by the high resolution (e, 2e) spectrometer with 0.5 eV energy resolution. The individual electron momentum distributions for the outer valence orbitals including the two Jahn-Teller splitting components for the highest occupied molecular orbital 3e(') have been(More)
A high-sensitivity angle and energy dispersive multichannel electron momentum spectrometer with simultaneous detection in 2π angle range is presented. A newly designed double half wedge and strip anode position-sensitive detector is employed to collect the ionized and scattered electrons passing through a 90° sector, 2π spherical electrostatic analyzer over(More)
We report the first measurement on vibrationally resolved electron momentum spectroscopy of H2 by using a high-resolution (e, 2e) spectrometer. The vibrational-specific experimental momentum profiles have been obtained and shown to be in agreement with calculations of (e, 2e) ionization cross sections taking into account the vibrational wave functions.(More)
The extensive study of outer- and inner-valence satellites of carbon dioxide by electron momentum spectroscopy is reported. The experiments have been performed using a high-sensitivity electron momentum spectrometer employing non-coplanar symmetric geometry at impact energy of about 1200 eV. Binding energy spectrum up to 50 eV, above the first double(More)
The fragmentation dynamics of OCSq+ (q = 2, 3, 4) induced by electron collision at an impact energy of 500 eV is studied. By using the momentum imaging technique, the three dimensional momentum vectors of all the fragments are obtained, which enables us to analyse both the kinetic energy release and the momentum correlations for a certain fragmentation(More)
The valence-shell binding energy spectra and electron momentum profiles of gaseous ethylamine are measured by (e, 2e) electron momentum spectroscopy. When taking into account the Boltzmann-weighted abundance of 39% for trans and 61% for two equivalent gauche conformers coexisted in ethylamine, the thermally averaged electron momentum profiles for all(More)
Vibrational effects on electron momentum distributions (EMDs) of outer-valence orbitals of oxetane are computed with a comprehensive consideration of all vibrational modes. It is found that vibrational motions influence EMDs of all outer-valence orbitals noticeably. The agreement between theoretical and experimental momentum profiles of the first five(More)
The binding energy spectra (BES) of valence shells of CH2BrCl and CF2BrCl have been measured at a series of different azimuthal angles by an (e, 2e) electron momentum spectrometer employing noncoplanar symmetric geometry at an impact energy of 1200 eV plus binding energy. The experimental momentum profiles (XMPs) are extracted from the sequential BES and(More)
