Abstract

We have studied the competition between different decay modes such as binary, ternary, cluster radioactivity and alpha decay. The competition between different decay modes plays a very important role in identifying the existence of the compound nuclei. The competition between different decay modes are studied using half-lives, penetration probability and amount of energy released during the fission/decay process. From this study it is observed that the superheavy nuclei 268–281Ds survive fission and undergo alpha decay and the nuclei 261–265Ds undergo spontaneous fission. We have also predicted the decay chains of the 268–281Ds. The present work is compared with the experiments available in the literature. The predicted isotopes with their half-lives will provide further investigations on the synthesis of more isotopes of Ds.

达姆施塔特姆不同衰变模式的研究

摘要

我们研究了不同衰变模式之间的竞争,例如二元,三元,团簇放射性和α衰变。不同衰变模式之间的竞争在识别化合物核的存在中起着非常重要的作用。使用半衰期,渗透概率和在裂变/衰变过程中释放的能量来研究不同衰变模式之间的竞争。从这项研究中可以观察到,超重核268–281 Ds能够在裂变中幸存,并经历α衰变,而核261–265 Ds则经历自发裂变。我们还预测了268–281的衰变链Ds。将当前工作与文献中提供的实验进行比较。预测的同位素及其半衰期将为更多Ds同位素的合成提供进一步的研究。
