“…For the 5.620 MeV c~ line, a half life was found of 32(13) s which is consistent with the half life of the ~88pb nucleus. The latter was estimated by Toth et al [16] to be >40. This 7 ray is the known E2 transition between the 2+ and the groundstate [13].…”

The e decay of mass-separated 18Spb and 18~has been studied at the GSI on-line mass separator. Alpha singles spectra as well as a :-X -t and e-e -t coincidence events were collected. Fine structure in the e decay of 188pb was measured for the first time, feeding the 2 + and 0~-states in 184Hg. The e decay of ~8~ feeds low-lying states in 176'178pt. One of these states could be identified as a 0 + state. The deexcitation pattern could be established. As a by-product an alpha-decay scheme of 18~ towards levels in 176Ir is given. The experimentThe 188pb and 18o, 182Hg isotopes were produced at the GSI mass-separator facility at Darmstadt, in the following fusion-evaporation reactions:

“…For the investigation of the a decay of ~sspb, the a detector and the LEGe detector were installed at the implantation station. [7] is not possible. This highlyconverted transition gives rise to KX-ray intensity from thallium as the EC decay of ~88pb does, but by using the time information (6 spectra of 12 s each) we could clearly separate the two components present in the KX rays.…”

“…Two transitions (185.0 and 758.2 keV) belonging to the /3 decay of 188pb were reported and only the total intensity -gamma plus conversion -of these transitions was given [7] (note however that the compilers in reference [16] give the gamma-ray intensity). Based on systematics, a M1 + E2 and E1 multipolarity was suggested for the 185.0 and 758.2 keV transitions respectively [7].…”

“…A strong increase in the 0 2 values when going from 186pb to 192pb was observed, in complete contradiction with an expected decrease if one approaches the N = 126 neutron-shell closure. Later on, Toth et al measured (partly remeasured) the a-branching ratios of the even t84, 186, 188,190,194pb isotopes [5][6][7][8][9] based on a comparison between the a intensity and the fl +/EC-delayed gammaray intensity.

“…This so-called "lead anomaly" was not reproduced by theoretical calculations [4]. They constructed level schemes for the even 188-194T1 nuclei populated via the beta decay of the corresponding lead isotopes [5][6][7][8][9][10].

The a-branching ratios (b~) of 192'19~ are measured using mass-separated sources. Different experimental setups are used -one detector as well as two detector set-ups -thereby detecting the ~ particles from the parent and/or via a decay formed daughter nuclei, the fl-delayed gamma radiation from the parent and/or via fl decay formed daughter nuclei and the T1 KX rays from electron capture decay. Values for b= of 6.2(6) 10 -5 and 4.0(4) 10 -3 were found for i92'19~ respectively. For 188pb, limits on the b~ values were obtained: 0.03
