MacNuclide is a novel software tool for accessing and visualizing nuclear data. This application incorporates a novel database management and visualization tools into an intuitive interface. The nuclide chart is used to access properties and to display results of searches. Selecting a nuclide in the chart displays a level scheme with tables of basic, radioactive decay, and other properties. All level schemes are interactive, allowing the user to modify the display, move between nuclides, and to display entire daughter decay chains. Nuclides can be searched for a variety of properties and attributes. Standard properties include mass, half life, spin-parity, decay mode, decay energy, decay branch, isomer energy, isotopic abundance, and neutron cross sections for capture, scattering, and fission. Mass is expressed in terms of mass, mass excess, binding energy, and binding energy per nucleon. Custom data can be imported from text files or can be generated for reaction Q-values and separation energies. Version 2 of the software application MacNuclide is a substantial improvement over version 1.0, offering a number of new features and including advanced display and handling of nuclear data. At the time the manual was written, nearly all the code was in place and in usable form. We have decided to accelerate the release of the software by phasing in features and offering multiple releases. A summary of the releases is given below. The ordering may change depending on the ease of installation and testing. Read More about MacNuclide Version 2 Girls Gone Wild
