The quartic isobaric multiplet mass equation
(Elsevier, 1969-05-05)
The quadratic isobaric multiplet mass equation must be replaced by an expression which is quartic in Tz if the electrostatic interaction is treated in second-order perturbation theory. The coefficients of the cubic and ...
Hyperfine Structure of Sodium Iodide
(The American Institute of Physics, 1969-05-01)
A molecular‐beam electric resonance spectrometer has been used to study radio‐frequency transitions between the hyperfine‐structure sublevels of the J = 1J=1 state of 23Na127I. Transitions for the first four vibrational ...
Quasielastic Scattering of Thermal Neutrons by CH3OH and CH3SH
(The American Institute of Physics, 1969-12-15)
We report measurements of the line broadening of thermal neutrons quasielastically scattered from room temperature methyl alcohol and methyl mercaptan in the liquid phase. The linewidths for CH3SH are found to be approximately ...
Generalized seniority for favored J [not equal to] 0 pairs in mixed configurations
(Elsevier, 1969-11-03)
By assigning a pseudo-spin and pseudo-orbital angular momentum (b-spin and c-spin) to the single-particle states in a mixed configuration of identical nucleons, it is possible to classify as B = 0 objects both the favored ...
Detection of Metastable Atoms and Molecules with Continuous Channel Electron Multipliers
(The American Institute of Physics, 1969-09)
On the Wigner Supermultiplet Scheme
(The American Institute of Physics, 1969-09)
Calculation of Wigner and Racah coefficients for the group SU(4)⊃[SU(2)×SU(2)]SU(4)⊃[SU(2)×SU(2)] make it possible to perform the spin—isospin sums in the cfp (fractional parentage coefficients) expansion of the matrix ...
Properties of Magnetically Balanced Arcs
(The American Institute of Physics, 1969-10)
Experimental results on steady magnetically balanced arcs in supersonic external flows are presented and analyzed, along with investigations elsewhere in subsonic flows, to determine the important similarity parameters. ...
Single Crystal Transfer Device and Rotation System for ESR Measurements
(The American Institute of Physics, 1969-02)
A device has been designed for the transfer and rotation of single crystals so that angular dependent ESR data can be obtained with a stationary magnet and rectangular cavity. The apparatus consists of a modified Donnay ...
ESR Spectrum of the 9‐Molybdomanganate(IV) Ion in Dilute Single Crystal
(The American Institute of Physics, 1969-05-01)
The ESR spectrum of a single crystal of (NH4)6[NI(IV)O6Mo9O26]⋅8H2O containing 1% (NH4)6‐[Mn(IV)O6Mo9O26]⋅8H2O has been investigated. This is the first ESR report on quadrivalent manganese in a chemically well‐characterized ...
Nonlinear Perturbations
(The American Institute of Physics, 1969-06)
The perturbation theory of Bogoliubov and Mitropolsky for systems having a single rapid phase is generalized to systems having several rapid phases. It is shown that one can avoid the classic problem of small divisors to ...
