“…These T 1/2 are not consistent with the reported value of 0.553 (46) s deduced from the time distribution of β rays in the β ray of 140 I from the same EURICA data [23]. And also, these T 1/2 do not correspond to the reported values of 0.59(1) and 0.86(4) s, which were determined in experiments of fission fragments using a mass separation system [25] and a gas-flow system [26,27], respectively. To solve this discrepancy between these T 1/2 , an additional isomer may be expected with longer T 1/2 than those of the g.s.…”

“…6(a). This T 1/2 of 0.91(5) s corresponds to 0.86(4) s [26,27]. Therefore, the half-lives of 0.553 (46) s [23] and 0.59(1) s [25] are presumed to correspond to a mixture of the components of the β decay of the g.s., HSI, and this low-spin isomer (LSI) in 140 I.…”

“…Spin and parity (I π ) are taken from Ref. [27]. The intensity of the γ ray and β ray (I β ) are normalized to the 377-keV γ -ray intensity.…”

Large scale accelerator production of 225Ac: Effective cross sections for 78–192 MeV protons incident on 232Th targets

“…The principal γ-ray energies, intensities, and appropriate branching ratios (if necessary) used in this study (Table 2) were acquired from the Nuclear Data Sheets (Artna-Cohen, 1997; Browne, 2001;Burrows, 2001;Sonzogni, 2001;Browne, 2005;Basunia, 2007;Kumar Jain et al, 2007;Nica, 2007;Browne and Tuli, 2011;Singh et al, 2011;Browne and Tuli, 2012;Nica, 2014).…”

Study of impact factors on the decay heat calculation of neutron sufficient even-even nuclei of Te, Xe, Ba, Ce, Nd and Sm isotopes

“…Considering QRPA calculation, it could be seen clearly that for each isotope chain, the calculated deviation would increase with the neutron number, which also means the increase of the deformation. For gross calculation, the better results got for 138 Xe, 140 Xe, 144 Ba, 154 Nd and 158 Sm nu- [22][23][24][25][26][27][28][29][30][31][32][33] and calculated E β by the Gross [21,22] and QRPA; (e) Comparison between experimental [22][23][24][25][26][27][28][29][30][31][32][33] and calculated E γ by the Gross [21,22] and QRPA Table 1.
