Chemical identification and properties of element 112.

Original language description

We present results of the second experiment on the chemical identification of element 112. Similar to the first test in 2000 [1], we aimed at the production of the spontaneously fissioning (283)112 nuclei with T-1/2 approximate to 3 min. A (U3O8)-U-nat (with some Nd) target, 2 mg of U/cm(2) thick, was bombarded with 233-MeV Ca-48 ions (the energy in the middle of the target layer). The nuclei recoiling from the target were thermalized in flowing helium. The target chamber was connected through a 25 m long capillary to detectors of alpha-particles and fission fragments. All the equipment and detectors were kept at ambient temperature. According to the test experiments, of all the heavy elements produced in the bombardment, only Hg, Rn and At could be transported to the detectors. The first detecting device was similar to that used earlier [1] an assembly of 8 pairs of PIPS detectors coated with gold. Here one would observe the decay of element 112 atoms if they like Hg adsorbed on gold.
