Machine Learning Assisted Parametrisation and Prediction of Bare to Neutral $β^{-}$ Decay Rate Ratios of Fully Ionised Atoms

Arkabrata Gupta, Spandan Aich, Suparna Sau +1

The β^- decay scenario of a nucleus differs significantly from its terrestrial characteristics when the atom is highly ionised or fully stripped of its electrons. Under such condit…

Allowed $β^{-}$ decay of bare atoms with A $\sim$ 60-80 in stellar environments

Arkabrata Gupta, Chirashree Lahiri, S. Sarkar

We have calculated $β^{-}$ decay rates to the continuum and bound states of some fully ionized atoms in the stellar s-process environment having free electron density and temperature…

Bound and continuum state $β^{-}$ decay of bare atoms: enhancement of decay rate and changes in $β^{-}$ decay branching

Arkabrata Gupta, Chirashree Lahiri, S. Sarkar

We have calculated rates of $β^{-}$ decay to both continuum and bound states separately for some fully ionized (bare) atoms in the mass range A $\approx$ 60-240. One of the motivat…
