Description
The mass of nuclides far from stability provides information on decay and reaction
energies that is crucial for modeling stellar nucleosynthesis.
Low production rates, short half-lives, and the inherent precision required make
masses perhaps the most difficult nuclear quantity to measure.
The minuteness of the binding energy has also contributed to confounding attempts
at reliable theoretical mass predictions.
This talk will introduce the role played by masses in astrophysics and then quickly
review and compare the (growing) multitude of mass-measurement programs now active
worldwide. The evaluation process that links reaction, decay and binding energies
is also described with its production of a benchmark for the development of the the
mass models required by nucleosynthesis networks.
