At fusion of two nuclei of deuterium the energy is generated. The reaction $D^2_1 + D^2_1 -> He^4_2 + 25 Mev$ is not observed. Instead of it strange reactions $D^2_1 + D^2_1 -> He^3_2 +n$ and $D^2_1 + D^2_1 -> T^3_1 + p$ with formation of nine-quark structures are going. Experimentalists had finished the investigation of $\mu$ - catalysis of of the DD reaction and have moved to an examination of the catalysis of the DD reaction on surface of platinum.
