Abstract
We discuss the connection of high-energy gamma-ray measurements with precis ion atomic mass determinations. These rather different technologies, proper ly combined, are shown to lead to new values for the neutron mass and the m olar Planck constant. We then proceed to describe the gamma-ray measurement process using the GAMS4 facility at the Institut Laue-Langevin and its app lication to a recent measurement of the 2.2 MeV deuteron binding energy and the neutron mass. Our paper concludes by describing the first crystal diff raction measurement of the 8.6 MeV Cl-36 binding energy.
