Abstract :
The single ion Penning trap mass spectrometer at M.I.T. can compare masses to within 0.1 parts per billion. We have created a short table of fundamental atomic masses and made measurements useful for calibrating the X-ray standard, and determining Avogadro´s number, the molar Plank constant, and the fine structure constant.<>
