Photoelectron spectroscopy of GaX[sub 2][sup -], Ga[sub 2]X[sup -], Ga[sub 2]X[sub 2][sup -], and Ga[sub 2]X[sub 3][sup -](X=P,As). Electron affinities, electronic term values, and vibrational frequencies are reported and compared to electronic structure calculations. In additi...
Science Chemistry Electron configuration Which of the following ions have a complete valence-shell octet? B^+, I^-, Ca^2+, or Pb^2+Question:Which of the following ions have a complete valence-shell octet? B^+, I^-, Ca^2+, or Pb^2+...
Electron-paramagnetic-resonance spectroscopy, band-structure calculations, polarization-voltage measurements, and charge injection experiments are used to show that Pb2+ ion displacements are critical to the ferroelectric behavior of Pb(Zr,Ti)O3. The displacements of the Pb2+ ions are followed by analy...
To describe the changes occurring inside the grains during time, Fig.2c–fshow a sequence of electron diffraction patterns (EDPs)taken during time in the area of the sample shown in Fig.2a. The starting arrangement of the lattice is provided in Fig.2cwherein specific rings of the tetragonal...
multi-configuration Dirac–Fock methodWe have used relativistic distorted-wave method to study electron-impact excitation of the fine-structure transitions from the 6 s 2 6 p 2 P 1/2,3/2 states to the excited 6 s 2 6 d 2 D 3/2,5/2 , 6 s 6 p 2 2 D 3/2,5/2 and 6 s 2...
One can compare the results of the cross section in the p–Pb and Pb–p peri- ods, and one can compare the results of the electron and the muon decay channels. The cross sections agreed in all cases Table 2 Summary of the contributions to the systematic uncertainty, in percent, for ...
