Analysis of the Spectrum of Doubly Ionized Molybdenum (Mo III)
The spectrum of doubly ionized molybdenum (Mo III) was produced in a sliding spark discharge and recorded photographically on the NIST 10.7-m normal incidence spectrograph in the 800-3250 Å spectral region. The analysis has led to the establishment of 76 levels of the interacting 4d4, 4d3 5s and 4d2 5s2 even configurations, 73 levels of the interacting 4d3 5d and 4d3 6s even configurations, and...
متن کاملThe Spectrum of Doubly Ionized Tungsten (W III)
The spectrum of doubly ionized tungsten (W III) was produced in a sliding-spark discharge and recorded photographically on the NIST 10.7-m normal-incidence vacuum spectrograph in the 600-2680 Å spectral region. The analysis has led to the establishment of 71 levels of the interacting 5d4, 5d3 6s and 5d2 6s2 even configurations and 164 levels of the interacting 5d3 6p and 5d2 6s 6p odd ones. A t...
متن کاملFission of doubly ionized calcium clusters
Cluster ions, CaN and Ca 2þ N , containing up to N = 8 atoms are studied within density functional theory. Ground and first excited states, and ionization energies are reported for all sizes. At zero temperature Ca2þ 3 and Ca 2þ 4 are linear, whereas Ca 2þ 5 through Ca 2þ 7 undergo structural transitions from 3D-configurations into linear ions below 600 K. As a consequence, fission that occurs ...
متن کاملLifetimes of doubly K-shell ionized states
The present work provides a reliable interpretation of the K α1/K α2 intensity ratios and an explanation of the lifetime values for K -shell hollow atoms based on an advanced theoretical analysis (using extensive multiconfiguration Dirac–Fock calculations with the inclusion of the transverse Breit interaction and quantum electrodynamics corrections). It was found that, as a result of closing th...
متن کاملThermodynamic properties of the ionized gas 3He
In this article, we have calculated some thermodynamic properties for a system consisting of singy ionized 3He atoms and their corresponding removed electrons by employing the second quantization method at finite temperature. To perform the calculations, we have considered the kinetic term, and Coulomb interaction between the particles in our Hamiltonian. The calculated properties are free ener...
