Prof. Albert Steyerl works in experimental neutron physics with main interests in ultra-cold neutrons (UCN) and neutron optics. He collaborates with physicists at Kyushu University (Japan), the Institut Laue-Langevin, Grenoble (France), and Harvard University in studies of the properties of ultracold neutrons. These neutrons have energies of 10-7 eV or less and are totally reflected for any angle of incidence on a wall made of a suitable material. Due to this property, the UCN can be stored in special UCN traps for hundreds of seconds.
Prof. Steyerl's research is focused on a precise measurement of the neutron lifetime for beta-decay. These experiments require UCN traps with special wall materials where the UCN are reflected thousands of times with very small loss probability. Another application of UCN is the search for an electric dipole moment of the neutron. Both the electric dipole moment and the lifetime of the neutron are of fundamental importance in theories of elementary particles, in astrophysics and in cosmological models.
