The article focuses on the assertion of Hans Klapdor-Kleingrothaus and his colleagues at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany that they have seen a rare form of radioactivity. It mentions that the Heidelberg-Moscow experiment was built from 11.5 kilograms of germanium, and started generating data in 1990. Stefan Schönert says that the nobel prize would go to Klapdor-Kleingrothaus if the claim were confirmed.
