Description
The compilation1 of the beta-decay rates, based on the method developed in PART
I,2 has been extensively used for various s-process models. Given the advent of a
sophisticated modeling of the s-process associated with the thermal pulse/inter-pulse
and 3rd dredge-up phase in low-mass stars, and of a possibility of the s-processing
in the core/shell carbon burning phase in massive stars, it may be worth improving
the beta-decay formalism in PART I on some fronts: 1) updating nuclear input data
(ft-values, Q-values), 2) estimating the possible errors in the computed rates, 3) extending
the temperature- and density- domains, and 4) removing various approximations
and inter-/extrapolations that were necessary in PART I because of the limited computational capabilities and budget (!). This contribution mainly concerns the item 3) & 4).
