DESCRIPTION:Prof. Giorgio Benedek\nDipartimento di Scienza dei Materiali\,
  Universitá di Milano-Bicocca\, Milano\, Italy\, &\nDonostia Internationa
 l Physics Center (DIPC)\, San Sebastian\, Spain\n"The Quantum Sonar: Mode-
 selected electron-phonon interaction in Pb ultrathin films measured by He 
 atom scattering."\n\nThe seminar illustrates how the gentlest of all surfa
 ce probes\, helium atoms\, which just tickle the surface 3 Å above the fi
 rst atomic plane\, can listen to the phonons of a metal ultra-thin film\, 
 even 7 layers beneath the surface\, and tell us about their interaction wi
 th electrons. In summary it will tell:\na) A brief history of skin and bon
 es\nb) How HAS perceives underground phonons of metal surfaces via electro
 nic excitations\nc) How HAS provides mode-selected e-p coupling of metal f
 ilms
