We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magnetic fields with ultracold neutrons (UCN). Our measurement stands in the long history of EDM experiments probing physics violating time reversal invariance. [...]

A Revised Experimental Upper Limit on the Electric Dipole Moment of the Neutron
/ Pendlebury, J M (Sussex U.) ; Afach, S (PSI, Villigen ; Zurich, ETH) ; Ayres, N J (Sussex U.) ; Baker, C A (Rutherford) ; Ban, G (Caen U.) ; Bison, G (PSI, Villigen) ; Bodek, K (Jagiellonian U) ; Burghoff, M (Berlin, Phys. Tech. Bund.) ; Geltenbort, P (Laue-Langevin Inst.) ; Green, K (Guelph U. ; Rutherford) et al.
We present for the first time a detailed and comprehensive analysis of the experimental results that set the current world sensitivity limit on the magnitude of the electric dipole moment (EDM) of the neutron. We have extended and enhanced our earlier analysis to include recent developments in the understanding of the effects of gravity in depolarizing ultracold neutrons (UCN); an improved calculation of the spectrum of the neutrons; and conservative estimates of other possible systematic errors, which are also shown to be consistent with more recent measurements undertaken with the apparatus.

Gravitational Depolarization of Ultracold Neutrons: Comparison with Data
/ Afach, S (Zurich, ETH) ; Ayres, N J ; Baker, C A (Rutherford) ; Ban, G (Caen U.) ; Bison, G (PSI, Villigen) ; Bodek, K (Jagiellonian U.) ; Fertl, M (PSI, Villigen ; Zurich, ETH) ; Franke, B (PSI, Villigen ; Zurich, ETH) ; Geltenbort, P (Laue-Langevin Inst.) ; Green, K (Guelph U. ; Rutherford) et al.
We compare the expected effects of so-called gravitationally enhanced depolarization of ultracold neutrons to measurements carried out in a spin-precession chamber exposed to a variety of vertical magnetic-field gradients. In particular, we have investigated the dependence upon these field gradients of spin depolarization rates and also of shifts in the measured neutron Larmor precession frequency. [...]

Preparation and characterization of a $^{39}Ar$ sample and study of the $^{39}Ar(n_{th},\alpha)^{36}S$ reaction
/ Goeminne, G ; Denecke, B ; Geltenbort, P ; Johansson, L ; Köster, U ; Pommé, S ; Wagemans, C ; Wagemans, J
The $^{39}$Ar(n$_{\rm th}$,$\alpha$)$^{36}$S reaction has been studied for the first time. A sample containing $2.85 \times 10^{14}$ $^{39}$Ar atoms, was produced at the ISOLDE facility at CERN. [...]
