“…There are indeed numerous cases where a decay transition is allowed by more than one form of multipole-such as the M1-E2 interference observable in Pb [39]. Moreover the received usage cultivates a misconception; that there exists the possibility of longrange communication of multipolar character, from an atom or molecule in which an emissive or absorptive multipolar transition occurs.…”

The premise that multipolar decay should produce photons uniquely imprinted with a measurably corresponding angular momentum is shown in general to be untrue. To assume a one-to-one correlation between the transition multipoles involved in source decay and detector excitation is to impose a generally unsupportable one-to-one correlation between the multipolar form of emission transition and a multipolar character for the detected field. It is specifically proven impossible to determine without ambiguity, by use of any conventional detector, and for any photon emitted through the nondipolar decay of an atomic excited state, a unique multipolar character for the transition associated with its generation. Consistent with the angular quantum uncertainty principle, removal of a detector from the immediate vicinity of the source produces a decreasing angular uncertainty in photon propagation direction, reflected in an increasing range of integer values for the measured angular momentum. In such a context it follows that when the decay of an electronic excited state occurs by an electric quadrupolar transition, for example, any assumption that the radiation so produced is conveyed in the form of "quadrupole photons" is experimentally unverifiable. The results of the general proof based on irreducible tensor analysis invite experimental verification, and they signify certain limitations on quantum optical data transmission.

“…This work is a continuation of our earlier studies of the hfs and Zeeman structures of heavy atoms [13][14][15][16][17][18][19][20][21][22][23][24]. Measurments were performed to investigate fourteen strongest emission lines in the near visible and infrared region of isotope 123 Sb (see Fig.…”

“…In the experiment the metallic isotope 123 Sb was used. A standard experimental arrangement for observation of hfs and Zeeman structures described in details in a series of our previous papers [13][14][15][16][17][18][19][20][21][22] was used. An electrodeless discharge tube powered by a RF generator (55 MHz) was the source of radiation.…”

Abstract. The hyperfine and Zeeman structures of 14 lines of isotope123 Sb covering the UV-NIR spectral range have been measured. The experimental data have been used in order to reanalyse and revise Sb I energy levels. We named majority of them for the first time since they were previously labelled only by their energy values, without any term designations. In both cases of odd-and even-parity levels we took into consideration up to 7 interacting configurations; the set of fine structure parameters and the leading eigenvector percentages of levels as well as their calculated Landé-factors are given. Semi-empirical hfs parameter values extracted from experimental data were compared with ab initio results computed by the use of Cowan code.

“…We have used a software developed in our group (for details see [15]), which proved its usefulness for many elements, e.g. Antimony [16,17], Lead [18], Bismuth [19][20][21], Lanthanum and Praseodymium [23,24]. In case of the Nd isotopes with hyperfine structure, 143 and 145, in simulations we have used the most recent hyperfine constants reported by [5,6,8].…”

Abstract. The Zeeman splitting at moderate magnetic fields (up to 334 G) of 20 lines of Nd II, covering the part 569.89 nm to 617.05 nm of the visible spectral range were investigated. We used a Doppler-free collinear laser ion beam spectroscopy technique supported by a precise computer analysis. From the Zeeman effect studies we re-investigated the Landé gJ factors for 20 odd levels between 22 850 and 30 002 cm and 11 even levels lying between 6005 and 12 460 cm −1 . We compared our data with other available experimental and theoretical values. We achieved an accuracy better than that of other authors, making our data valuable for future theoretical parametric studies.
