Jeffrey S. Nico

Research Interests:

My research interests have centered around studies fundamental physics using neutrons and the field of neutron detection and dosimetry. In particular, I have been involved in experiments to measure the neutron lifetime, the time-reversal violating D coefficient, and radiative neutron decay. I am also interested in hadronic parity violation and am a collaborator in an experiment to measure the spin rotation of polarized neutrons in a liquid helium target. I have a continued interest in neutrino physics and have been a collaborator in the SAGE solar neutrino experiment since 1991. I work in the field of neutron standards and dosimetry and help to maintain neutron fields with thermal and fast neutrons at NIST. I collaborate in efforts to improve the detection and spectroscopy of fast neutrons.
