Comparison of nuclear mass models at nuclearmasses.org

Nuclear masses are crucial in many astrophysics studies, as well as other areas of basic and applied nuclear science. There are now many different global theoretical models of nuclear masses – but choosing the best model for a given application can be challenging. The suite of codes online at nuclearmasses.org greatly facilitates the comparison of nuclear models with evaluated masses as well as the intercomparison of theoretical models. We demonstrate the utility of this suite by comparing the RMS deviations of 13 different theoretical mass models from the AME2003 evaluated masses over mass ranges appropriate for astrophysics.
