Abstract: (Springer)
A method is proposed for conducting an experimental search for inelastic interactions of weakly interacting massive particles (WIMPs) involving the excitation of long-lived levels of73Ge nuclei. Analysis of the first experimental results has made it possible to obtain the background level for these reactions as 0.0013 events/(ke V·kg (73Ge)·day). Experimental limits are obtained as to the cross section for spindependent inelastic interactions of WIMPs with73Ge nuclei.- WIMP: nuclear reaction
- germanium: energy levels
- background
- spin dependence
- WIMP: mass
- channel cross section: mass
- experimental methods: proposed
- numerical calculations
