Ionization Rates in (AlxGa1−x)As
(The American Institute of Physics, 1970-10)
The ionization rates of (AlxGa1−x) As have been measured as a function of the Al content and the results are presented here. Values of both A and b are found to increase with Al content. It is also found that for low values ...
S-wave non-leptonic decays and gauge fields
(Elsevier, 1970-11-01)
S-wave non-leptonic decay amplitudes are obtained from a gauge-field model and the results are also interpreted from the point of view of mixing of particle fields. The model gives different effective enhancements for K- ...
On the Asymptotic Stability of Reactors with Arbitrary Feedback
(The American Institute of Physics, 1970-01)
A theorem for the boundedness and asymptotic stability of a point reactor with an arbitrary feedback is stated and proved. The criteria obtained are shown to be essentially the same as those given by Akcasu and Dolfes. The ...
Electron Relaxation and Molecular Vibrations: Triatomic Systems of the First‐Row Elements, the Methyl Radical, and Diazomethane and Ketene
(The American Institute of Physics, 1970-03-15)
The well‐known second‐order perturbation method is used to correlate the bond–bond interaction constants in ground and excited electronic states of triatomic systems of the first‐row elements, and unusual force constants ...
Hyperfine Structure of Thallium Bromide
(The American Institute of Physics, 1970-08-15)
The hyperfine structure of the J = 2J=2 and J = 3J=3 rotational states of TlBr has been measured with a molecular‐beam electric resonance spectrometer. Hyperfine transition frequencies were measured under conditions ...
Raman spectra and vibrational assignments for 1,1,1-trihaloethanes and their deuterium derivatives
(Elsevier, 1970-04)
Raman spectra of the first three members of the 1,1,1-trihaloethane series, CH3CX3, X = F, Cl, Br, were obtained for the liquids under low resolution. All but two active fundamental vibrational frequencies were observed, ...
On the decay of 148 Pm
(Springer-Verlag, 1970-10)
The Β-γ directional correlation between the 1,930 keV Β -group and the 511 keV cascade γ -ray in the 5.4 d 148 Pm decay has been measured at 14 different γ -energy points. The anisotropy is found to be positive and is ...
Absorption of He☒Ne Laser Radiation in an Exploded Lithium‐Wire Plasma
(The American Institute of Physics, 1970-03-15)
Calculations of the absorption coefficients for inverse bremsstrahlung in the field of ions and neutral atoms in ground and excited states and for photoionization are presented for the absorption of He☒Ne laser radiation ...
Injection and mobility of potassium ions in liquid helium
(Elsevier, 1970-05-04)
Potassium ions from a hot tungsten wire are injected into He II; their mobility is found to be two to three percent lower than that of `normal' positive ions.
Intermolecular Vibrations in Liquid Secondary Chlorides
