摘要
The superheavy hydrogen isotopes 4H and 5H have been investigated in the stopped pion absorption on 9Be. Three states of 4H were proposed in the reaction channel 9Be( { - }, dt)X. Four states of 5H were proposed in the reaction channels 9Be({ - }, pt)X and 9Be({ - }, dt)X. The excited states of 5H can decay into free nucleons.
