Abstract

The evaluated data are presented for 11 known A=218 nulcides (Pb, Bi, Po, At, Rn, Fr, Ra, Ac, Th, Pa and U). For ²¹⁸Pb, ²¹⁸Bi, ²¹⁸At and ²¹⁸Pa, data are available only for the ground states. For ²¹⁸U, only the g.s. and a high-spin isomer are known, with no data on γ-ray transitions available. For ²¹⁸Po, ten excited states are known from ²¹⁸Bi decay, with no knowledge on the multipolarities of gamma-ray transitions. For ²¹⁸Th, five excited states in the g.s. band are known from an in-beam γ-ray study. Data on level half-lives, multipolarities and mixing ratios of gamma transitions is generally lacking for A=218 nuclei. The static magnetic dipole moment has been measured for only an isomer in ²¹⁸Fr. With the exception of a new nuclide, ²¹⁸Pb, and measurements of half-lives of ground states of a few nuclides of A=218 and A=222, no substantial structure information has become available since the previous evaluation in 2006. Q values are adopted from 2017Wa10 (AME-2016). The present evaluation supersedes the previous A=218 ENSDF evaluations, 2006Ja03, 1995El08, 1987El12 and 1977To13. This evaluation was carried out as part of a joint IAEA-ICTP workshop for Nuclear Structure and Decay Data, organized and hosted by the IAEA, Vienna, and ICTP, Trieste, October 15–26, 2018.

Half-life determination of 215At and 221Ra with high-purity radioactive ion beams
2024, Applied Radiation and Isotopes
At CERN-ISOLDE, high-purity radioactive ion beams of ²¹⁹Fr and ²²¹RaF were investigated with $α$ -decay spectroscopy at the CRIS and ASET experiments in the course of three different experimental campaigns. The half-life of ²¹⁵At, $α$ -decay daughter of ²¹⁹Fr, is measured to be 36.3(3)[9] $μ s$ , and that of ²²¹Ra was determined to be 26.2(1)[6] s, both of which are well in line with the trends in this region of the nuclear landscape but at odds with some of the reported literature.
