 The Dubna team believes that the synthesis of the element is direct experimental proof of the existence of the island of stability.It has been calculated that the isotope 295Ts would have a half-life of about 18 milliseconds, and it may be possible to produce this isotope via the same berkelium–calcium reaction used in the discoveries of the known isotopes, 293Ts and 294Ts.The chance of this reaction producing 295Ts is estimated to be, at most, one-seventh the chance of producing 294Ts.
