• Proposed measurement of the beta-neutrino correlation in neutron decay

  Currently, the beta-neutrino asymmetry has the largest uncertainty (4%) of the neutron decay angular correlations. Without requiring polarimetry,...

• On the measurement of the electron-neutrino correlation in neutron beta decay

  I present a new approach to the measurement of a, the electron-neutrino correlation, in neutron beta decay. A precise measurement of a can lead to a...

• The beta-, neutrino- and proton-asymmetry in neutron [beta]-decay

  This article describes measurements of angular-correlation coefficients in the decay of free neutrons with the superconducting spectrometer PERKEO...

• Determination of the electron-antineutrino angular correlation coefficient [a.sub.0] in unpolarized neutron [beta]-decay

  The coefficient [a.sub.0] has been derived from a measurement of the integral spectrum of recoil protons stored in a quasi-Penning trap with...

• On the measurement of the neutron lifetime using ultracold neutrons in a vacuum quadrupole trap

  We present a conceptual design for an experiment to measure the neutron lifetime (~886 s) with an accuracy of [10.sup.-4]. The lifetime will be...

• Chaotic scattering and escape times of marginally trapped ultracold neutrons

  We compute classical trajectories of Ultracold neutrons (UCNs) in a supercon-ducting Ioffe-type magnetic trap using a symplectic integration method....
