NuDat 3.0Web application that allows users to search and plot nuclear structure and nuclear decay data interactively. It provides an interface between web users and several databases containing nuclear structure, nuclear decay and some neutron-induced nuclear reaction information. Using NuDat, it is possible to search for nuclear level properties (energy, half-life, spin-parity), gamma-ray information (energy, intensity, multipolarity, coincidences), radiation information following nuclear decay (energy, intensity, dose), and neutron-induced reaction data from the ENDF/B-VII.0 library (thermal cross section and fission yields).
