“…Our oscillator strength for the above transition match well with the tabulated result as 0.15 in [20]. Nonetheless, our results for the 5d states agree substantially with the results reported by Buchta et al [12].…”

“…Nonetheless, our results for the 5d states agree substantially with the results reported by Buchta et al [12]. The measured oscillator strength for the 3d → 4f transition is reported as 0.03 which differ completely from our result 0.14, but our result agrees with the results reported in [20]. With all the above observations, it is worth reiterating that the results reported in this work are more accurate and they can be used reliably in any other applications.…”

“…[12]. Some of the data reported by Wiese and Fuhr [20], as was mentioned in the previous paragraph, were actually quoted from these measurements. We have estimated the lifetimes of all the states that we have taken into account for our study using the transition rates given above and listed them in Table IV [12].…”

Transition properties such as oscillator strengths, transition rates, branching ratios and lifetimes of many low-lying states in the doubly ionized scandium (Sc III) are reported. A relativistic method in the coupled-cluster framework has been employed to incorporate the electron correlation effects due to the Coulomb interaction to all orders by considering all possible singly and doubly excited electronic configurations conjointly with the leading order triply excited configurations in a perturbative approach. Present results are compared with the previously reported results for the transition lines of astrophysical interest. In addition, some of the transition properties and lifetimes of few low-lying states are given for the first time. Role of the correlation effects in the evaluation of the transition strengths are described concisely.

“…1). This line is comparable in strength to C i λ9094.8 (the strongest in the 9100 Å group), the difference in excitation potentials being almost compensated by the difference in oscillator strengths (values in Table 2 are taken from Wiese et al 1996, as retrieved using the NIST Atomic Spectra Database version 3 3 ). It is thus still detected at the lowest metallicities ([Fe/H] < ∼ −3).…”

Aims. We present new measurements of the abundances of carbon and oxygen derived from high-excitation C i and O i absorption lines in metal-poor halo stars, with the aim of clarifying the main sources of these two elements in the early stages of the chemical enrichment of the Galaxy. Methods. We target 15 new stars compared to our previous study, with an emphasis on additional C/O determinations in the crucial metallicity range −3 < ∼ [Fe/H] < ∼ −2. The stellar effective temperatures were estimated from the profile of the Hβ line. Departures from local thermodynamic equilibrium were accounted for in the line formation for both carbon and oxygen. The non-LTE effects are very strong at the lowest metallicities but, contrary to what has sometimes been assumed in the past due to a simplified assessment, of different degrees for the two elements. In addition, for the 28 stars with [Fe/H] < −1 previously analysed, stellar parameters were re-derived and non-LTE corrections applied in the same fashion as for the rest of our sample, giving consistent abundances for 43 halo stars in total.

“…The calculations of the spontaneous one-photon decay rates can be done, in principle, within the framework of standard quantum electrodynamics and can be found, for example, in [21][22][23]. In particular, from Table II it follows that the transition probabilities W 1 and W 2 arising in the field contribute on the level of partial one-photon decay rates of the np states.…”

Rydberg-state mixing in the presence of an external electric field: Comparison of the hydrogen and antihydrogen spectra

We analyze the influence of an external electric field on the ns and np Rydberg states. The impact of an electric field leads to a significant modification of the decay rate. Namely, the additional (linear and quadratic in the field) terms arise in the differential transition probabilities. In contrast to the quadratic term, the linear summand leads to a difference of the hydrogen (H) and antihydrogen (H) spectra. However, this difference vanishes after the integration over photon-emission directions and does not contribute to the total emission probability. The quadratic term results in the significant change of the total decay rate and level width, respectively. The analysis of the linear and quadratic terms depending on the field strength is discussed.
