Leech therapy is currently considered to be of high therapeutic value in medicine. However, feeding leeches with fresh animal blood during the maintenance and reproduction phase bears the risk of transmission of zoonotic viruses to the patient. We hypothesize that this would be abolished by subjecting leeches to quarantine measures prior to use. The(More)
The dynamics of image-potential states on Cu(119) have been studied with two-photon photoemission. Direction-dependent quasielastic scattering processes with large momentum transfer are attributed to the finite terrace-width distribution on the stepped surface. This effectively couples image-potential states via interband scattering and leads to an(More)
