Search for an annual modulation of dark-matter signals with a germanium spectrometer at the Sierra Grande Laboratory

1999

Abstract Results of a search for dark-matter induced annual modulation using 830.5 kg·days of data collected at the Sierra Grande underground laboratory with a germanium detector are presented. The analysis of the data does not show any indication of seasonal effects.
