Weak Interaction Data

Resources for rates of reactions mediated by the weak interaction, such as beta-decay, electron capture, and neutrino interaction for use in astrophysical models.

Weak Rate Library

A new open source weak interaction rate library with the aim of standardizing the incorporation of weak rates in astrophysical simulations is now available. The library can also be used within the neutrino interaction library NuLib.

Terrestrial Beta-Decay and Electron Capture Rates

Terrestrial beta-decay and electron capture rates together with delayed particle emission branches are included in the reaclib data base. These rates should be corrected for density and temperature effects before they are used in astrophysical models.
