NuDat allows users to search and plot nuclear structure and nuclear decay data interactively NuDat 2 is a software product that allows to search and plot nuclear structure and nuclear decay data interactively. NuDat 2 was developed by the National Nuclear Data Center (NNDC). It provides an interface between web users and several databases containing nuclear structure, nuclear decay and some neutron-induced nuclear reaction information.
There are three different search forms: one for levels and gammas, a second one for decay-related information, and a third one for searching the Nuclear Wallet Cards file.
