| Abstract: | The decay pattern is investigated for new radioactive series. It is found that the necking effect of decay exists near A =235. The phenomena and characteristics are analyzed, and a preliminary explanation on the reasons of producing necking effect is carried out according to the model of nuclear configuration. |
