摘要: Abstract A search has been made for the superheavy isotope of hydrogen, 6H, whose existence claimed in two heavy ion experiments. The pion double charge exchange reaction 6 Li (π − , π + ) X at T(π−)= 220MeV was used a high-resolution 6H. No evidence 6H found anywhere missing mass range −10 to +30 MeV. In region 0–5 MeV 95% confidence upper limits nb/sr production cross section were set.
