英文摘要 | Double beta(-)-decay with two neutrinos is one of the important decay modes for an unstable nucleus which can spontaneously change into a stable nucleus. It is also a very complex decay process where three kinds of interactions, the strong interaction, the Coulomb interaction, and the weak interaction, are involved. Recently we have made a systematic analysis on the experimental data of nuclear double beta(-)-decay and proposed that there is a law between the logarithm of double beta(-)-decay half-lives and the reciprocal of the decay energy. This is a simple and accurate law for half-lives of the double beta(-)-decay. We use this law to predict the half-lives of the double beta(-)-decay candidates where the mass number of parent nuclei ranges from A=70 (Zn-70) to A = 204 (Hg-204). Numerical results of the half-lives show that Ce-142 is a very interesting candidate for future experiments to search new emitters of the double beta(-)-decay. We also compare the half-lives of double beta(-)-decay and alpha-decay for Ce-142 where its decay energies of two modes are close and find that double beta(-)-decay dominates in this case although double beta(-)-decay is a second order process of the weak interaction. The branching ratios between double beta(-)-decay and alpha-decay are listed for the candidates of double beta(-)-decay. |
