Precision Measurement of the 29Si, 33S, and 36Cl Binding Energies
M. S. Dewey, E. G. Kessler, R. D. Deslattes +4
The binding energies of 29Si, 33S, and 36Cl have been measured with a relative uncertainty using a flat-crystal spectrometer. The unique features of these m…
Measurement of the Neutron Lifetime by Counting Trapped Protons in a Cold Neutron Beam
J. S. Nico, M. S. Dewey, D. M. Gilliam +9
A measurement of the neutron lifetime performed by the absolute counting of in-beam neutrons and their decay protons has been completed. Protons confined in a quasi-Penning…
A Backscatter-Suppressed Beta Spectrometer for Neutron Decay Studies
F. E. Wietfeldt, C. Trull, R. Anderman +6
We describe a beta electron spectrometer for use in an upcoming experiment that will measure the beta-antineutrino correlation coefficient (a-coefficient) in neutron beta decay. El…
Measurement of the Neutron Lifetime Using a Proton Trap
M. S. Dewey, D. M. Gilliam, J. S. Nico +8
We report a new measurement of the neutron decay lifetime by the absolute counting of in-beam neutrons and their decay protons. Protons were confined in a quasi-Penning trap and co…
