Fragmentation dynamics of diatomic molecules under proton impact: Kinetic energy release spectra of CO^{q+} and NO^{q+} (q = 2, 3) molecular ions
Avijit Duley, Narendra Nath Dutta, C. Bagdia +3
We report on the fragmentation dynamics of triply charged, diatomic, molecular ions of NO and CO. Dissociative fragmentation after multiple ionization of NO and CO is studied under…
Two-photon polarizability of Ba ion: Control of spin-mixing process in an ultracold Ba--Rb mixture
Arghya Das, Anal Bhowmik, Narendra Nath Dutta +1
Ionic clocks exhibit as the most promising candidates for the frequency standards. Recent investigations show the profound advantages of interrogating two laser beams with differen…
Vector polarizability of atomic state induced by a linearly polarized vortex beam: External control of magic, tune-out wavelengths, and heteronuclear spin oscillations
Anal Bhowmik, Narendra Nath Dutta, Sonjoy Majumder
Experiments with vortex beams have shown a surge of interest in controlling cold atoms. Most of the controlling protocols are dominated by circularly polarized light due to its abi…
Precise many-body calculations and hyperfine interaction effect on dynamic polarizabilities at the low-lying energy levels of Y
Arghya Das, Anal Bhowmik, Narendra Nath Dutta +1
The present work determines the precise values of magic wavelengths corresponding to the clock transitions 5-4 of Y ion both at the levels of fine- and hyperfine-s…
Tunable magic wavelengths for trapping with focused Laguerre-Gaussian beam
Anal Bhowmik, Narendra Nath Dutta, Sonjoy Majumder
We present in this paper a theory of dynamic polarizability for an atomic state due to an external field of non-paraxial Laguerre-Gaussian (LG) beam using the sum-over-states techn…
Electron-correlation study of Y III-Tc VII ions using a relativistic coupled-cluster theory
Arghya Das, Anal Bhowmik, Narendra Nath Dutta +1
Spectroscopic properties, useful for plasma diagnostics and astrophysics, of a few rubidium-like ions are studied here. We choose one of the simplest, but correlationally challengi…
