Study of coupled-cluster correlations on electromagnetic transitions and hyperfine structure constants of W VI
Anal Bhowmik, Sourav Roy, Narendra Nath Dutta +1
This work presents precise calculations of important electromagnetic transition amplitudes along with detail of their many-body correlations using relativistic coupled cluster meth…
Precise calculations of astrophysically important allowed and forbidden transitions of Xe VIII
Anal Bhowmik, Narendra Nath Dutta, Sourav Roy
The present work reports transition line parameters for Xe VIII, which are potentially important for astrophysics in view of recent observations of multiply ionized xenon in hot wh…
Relativistic coupled cluster calculations on hyperfine structures and electromagnetic transition amplitudes of In III
Sourav Roy, Narendra Nath Dutta, Sonjoy Majumder
Hyperfine constants and anomalies of ground as well as few low lying excited states of In III are studied with highly correlated relativistic coupled-cluster theory…
Fragmentation of Positronium (Ps) in collision with Li ion
S. Roy, C. Sinha
Fragmentation of ground state ortho Positronium (Ps) in collision with Li ion (Li+) is studied in the framework of post collisional Coulomb distorted eikonal approximation (CDEA) f…
