SEARCH FOR INELASTIC INTERACTIONS OF WIMPS WITH EXCITATION OF GE-73 NUCLEI

A method is proposed for conducting an experimental search for inelast ic interactions of weakly interacting massive particles (WIMPs) involv ing the excitation of long-lived levels of Ge-73 nuclei. Analysis of t he first experimental results has made it possible to obtain the backg round level for these reactions as 0.0013 events/(keV.kg (Ge-73).day). Experimental limits are obtained as to the cross section for spin-dep endent inelastic interactions of WIMPs with Ge-73 nuclei. (C) 1998 Ame rican Institute of Physics. [S0021-3640(98)00111-X].
