重新评估Beck等人的数据,以限制Th-229异构体的能量

Re-evaluation of the Beck et al. data to constrain the energy of the Th-229 isomer

Georgy A. Kazakov, Thorsten Schumm, Simon Stellmer

摘要:

目前公认的Th-229基态双重态的能量分裂值是在Beck等人的非直接γ谱测量的基础上获得的,物理修订版信函98,142501(2007)。从那时起,许多实验开始直接测量异构体的能量,但没有一个能观察到跃迁。在这里,我们进行了分析,以确定异构体能量和分支比的参数空间是一致的贝克等人。实验。

英文摘要:

The presently accepted value of the energy splitting of the Th-229 ground-state doublet has been obtained on the basis of undirect gamma spectroscopy measurements by Beck et al., Phys. Rev. Lett. 98, 142501 (2007). Since then, a number of experiments set out to measure the isomer energy directly, however none of them resulted in an observation of the transition. Here we perform an analysis to identify the parameter space of isomer energy and branching ratio that is consistent with the Beck et al. experiment.
