“…Using our previously reported E1 matrix elements in Ref. [61] and the experimental energies taken from the NIST database, we evaluate the static dipole polarizabilities of the ground and excited states of Mg + , Ca + , Sr + and Ba + ions. Then, we compare these values with the previously available experimental and theoretical results in Tables K, L, M and N. The scalar polarizabilities of the considered ground and excited states along with the tensor polarizabilities for the states with J > 1/2 are presented separately.…”

“…In this work, we intend to present data tables for the accurate values of quadrupole matrix elements for a large number of transitions of the above ions, E2 radiative properties, tune-out wavelengths and magic wavelengths of the Mg + , Ca + , Sr + and Ba + ions. We have estimated the quadrupole matrix elements and other related radiative properties of the transitions involving the nS of Ca + (n=4); Sr + (n=5) and Ba + (n=6) are presented using the dipole matrix elements given in our previous work [61]. Using these dipole dynamic polarizabilities, the magic wavelengths are obtained by locating the crossings between the dynamic polarizabilities of the nS 1/2 , nP 1/2 , nP 3/2 , nD 3/2 and nD 5/2 states of Mg + (n=3); nS 1/2 , nP 1/2 , nP 3/2 , (n − 1)D 3/2 and (n − 1)D 5/2 states of Ca + (n=4), Sr + (n=5) and Ba + (n=6) plotted against the wavelengths in the range 300-1300 nm.…”

Light shift in a state due to the applied laser in an atomic system vanishes at tune-out wavelengths (λTs). Similarly, differential light shift in a transition vanishes at the magic wavelengths (λmagics). In many of the earlier studies, values of the electric dipole (E1) matrix elements were inferred precisely by combining measurements and calculations of λmagic. Similarly, the λT values of an atomic state can be used to infer the E1 matrix element, as it involves dynamic electric dipole (α) values of only one state whereas the λmagic values require evaluation of α values for two states. However, both the λmagic and λT values depend on angular momenta and their magnetic components (M) of states. Here, we report the λmagic and λT values of many S1/2 and D3/2,5/2 states, and transitions among these states of the Mg+, Ca+, Sr+ and Ba+ ions that are independent of M values. It is possible to infer a large number of E1 matrix elements of the above ions accurately by measuring these values and combining with our calculations.

“…Different properties of Ba + such as energies, HFS constants, electric-dipole, and parity-nonconserving transition amplitudes were repeatedly calculated earlier using various methods [11][12][13][14][15][16][17][18][19][20][21][22]. Since Ba + is a univalent ion, most of calculations were carried out in the framework of relativistic coupled-cluster method, which is particulary well suited for such cases with only core-core and core-valence correlations.…”

We carried out calculations of the energies, hyperfine structure constants and electric-dipole transiton amplitudes for the low-lying states of Ba + in the framework of the relativistic linearized coupled-cluster single double (LCCSD) and coupled-cluster single double (valence) triple (CCSDvT) methods. Taking into account that an iterative inclusion of the valence triples into consideration is a complicated and computationally demanding process we study the effects of computational restriction on the final results. We also present a detailed study of various corrections to all calculated properties and use our results to formulate several broad rules that can be used in future calculations of the elements where experimental data are scarce and correct theoretical predictions are highly important.
