Scientific paper

An ultralow background Ge detector in the Homestake gold mine is applied to searches for 0 nu Beta-Beta-decay, cold dark matter candidates and invisible axions from the sun. A large body of low background Ge data imply (mnu) is less than or approximate to 2.3 eV. Particles with spin independent Z exchange interactions and masses between 20 GeV and 5 TeV are excluded as dominant in the galactic halo. Finally, axions with F(2x'e) is less than or approximate to 0.5 x 10 to the 7th power GeV are also ruled out.
