摘    要:讨论了超轴元素的自发裂变和α衰变对其存在界限的时间限制、裂变势垒和平均核结合能对其存在界限的能量限制以及合成超轴重元素的生成截面限制等。作者认为超铀元素存在的界限(或极限)大体在Z=110-125号元素,而Z=114-120号元素将更有可能。

关 键 词:周期系  超铀元素  界限

Abstract:The boundary limit of the periodic system is also one of the transuraniums.This is a sig-nificant question of fundmental theory.Some problems are discussed in this paper which include time—re-striction of transuranium's limit resulting from spontaneous fission and a decay,energy-restriction oftransuranium's limit resulting from fission barrier and everage nuclearbinding energy andcross-section-restriction to synthesis of the transuraniums.Authors consider that transuranium's limit isnot far from Z=109 element,it will be about Z=110-125 elements and more possible within Z=114-120elements.
Keywords:periodic system  transuranium  limit
