Electromagnetic Transition Probabilities
1994The calculation of electromagnetic transitions is a standard chapter of quantum mechanics, the essential formula being the famous “golden rule” (see, e.g., Heitler 1953, Messiah 1973). However, the resulting final expressions for field-free transitions or for Zeeman transitions which may be found in the literature cannot simply be applied to atoms in ...

Transition Probabilities in Xe V
Physica Scripta, 2005Transition probabilities have been calculated with the pseudorelativistic Hartree–Fock (HFR) approach in which core-polarization effects have been included for Δn = 0 and Δn = 1 transitions connecting the 5s25p2, 5s25p6p, 5s25p4f and the 5s5p3, 5s25p5d and 5s25p6s configurations of Xe V.

Asymptotic transition probabilities
Journal of Mathematical Physics, 1989The impact parameter model for the scattering of two heavy particles and a light one is studied. The asymptotic behavior of the transition probability is studied when the relative velocity of the heavy particles goes to zero. In particular, rigorous proof is given from first principles, within the context of the model, of the validity of Massey’s ...

Neon Transition Probabilities*
Journal of the Optical Society of America, 1968Relative transition probabilities for 12 visible neon lines originating on the 3s2 and 3s3 (Paschen notation) levels of neon have been measured. The experimental technique utilizes the interaction between the output of a helium–neon laser oscillating at 3.39 μ (3s2–3p4) and the excited atoms in a neon discharge.

Hilbert-space representations of transition probability spaces are studied. The notions of superposition and the superposition principle are introduced. It is shown that, provided the superposition principle and the postulate of minimal superposition are satisfied, transition probability space can be represented by a generalized Hilbert space.

Transition probabilities in neutral barium
Physical Review A, 1987We present emission measurements on a hollow-cathode discharge containing barium that were taken with the aid of a Fourier-transform spectrometer (FTS). We have determined the branching fractions for ten upper levels of the neutral barium atom. In the case of the resonance level 6s6p ${}^{1}$P\ifmmode^\circ\else\textdegree\fi{}${}_{1}$, we had to ...

The set of pure quantum states is described as an abstract space with a geometry determined by transition probabilities. We describe all possible structures for three-dimensional transition probability spaces with less than ten states, as well as some even larger spaces of a certain symmetric type.

Transition Probability and Dichotic Listening
Nature, 1973BLOOMFIELD1 has rejected the hypothesis that in a dichotic listening situation the selection of the attended message by the subject is based only on spatial cues, and argued that the transition probabilities between words also affects their selection. Physical cues rather than spatial ones should have been referred to because it has been demonstrated ...
