Using pulse shape analysis of data from 173 operating days of our 6.2 kg NaI detector in the energy range 7-10 keV we present new limits on weakly interacting massive particles that may constitute the dark matter. An improvement of a factor >30 has been obtained over Ge for spin-dependent dark matter interactions while limits for coherent interactions are comparable to Ge for masses > 100 GeV.

© 1995, by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved. The capability of observing gravitational radiation over a wide range of frequencies will open up major new opportunities in fundamental physics and astronomy. The Laser Interferometer Space Antenna (LISA) will be able to detect gravitational radiation over the frequency range from 0.1 mHz to 0.1 Hz with high sensitivity. Signals from hundreds to thousands of galactic binaries will be detectable. In addition, the coalescence of massive black hole binaries, which may have been produced by mergers of galaxies or of pregalactic structures, would be observable out to large redshifts. Such signals would allow the study of the interactions of large masses at small distances, which would not be possible in any other manner. LISA was proposed initially by a group of European and US scientists as a possible joint ESA/NASA mission, but has been studied recently as a candidate for a predominantly European mission. The results of the study indicated that the technology for the mission is available or will soon be available. The main part of the study team report given here summarizes the scientific objectives and the mission concept.
