“…We note that there is a 13 sigma discrepancy between the two recent most precise measurements [9,10], calling into question at least one of the quoted uncertainties. In such cases the Particle Data Group [12] recommends a procedure for scaling the uncertainty.…”

“…The predominant decay mode is via γ decay although particle emission mediated either by the strong force (α-decay), weak force (β-decay), or fission is also possible and observed. Isomeric lifetimes range from a few ns to 10 15 years for 180m Ta, longer than the accepted lifetime of the universe. The lifetimes of these excited states probe the detailed wave functions of the underlying nuclear structure.…”

“…The first published values (from 1958 and 1990) for the determination of the half-life used 177 Lu from the 176 Lu(n,γ ) 177 Lu reaction, however no correction was applied for the presence of the 177m Lu impurity, resulting in an overestimation of the half-lives values determined [6][7][8]10], with the exception of the value reported by Lagoutine and Legrand (1982) [9].…”

“…There have been 14 previous publications reporting half-life measurements of 177 Lu [6][7][8][9][10][11][12][13][14][15][16][17][18][19], which are summarised in Table 1. Of these only the measurement reported by Dryak et al [18] has used 177 Lu from production method 2) and therefore not required corrections for the 177m Lu impurity.…”

“…The correlation counting method is an alternative technique [3][4][5][6][7][8], based on the well known fact that decays of radionuclides follow Poisson statistics where the variance V of the distribution is equal to the mean value n, V = n. However, the principle is sometimes disturbed in cases such as 75 Se. This nuclide decays to 75 As by electron capture to several excited states of its daughter, as illustrated in figure 1 [9]. The isomer at 304 keV excitation energy decays via internal conversion and those electrons will be registered in the same particle detector at some finite time after disintegration together with parent events such as Auger electrons.…”
