The evidence obtained for the existence of the K X-ray gamma-ray directional correlation by Perepelkin against the predictions of the theory of Dolginov evoked considerable interest in this field. The electron capture decay of 114Inm is used to advantage in the present investigation with a sum-peak-coincidence scintillation spectrometer. The results obtained are consistent with the theory of Dolginov.

We have performed a new determination of the half-life of 41Ca by measuring the specific activity of an enriched Ca material with known 41Ca abundance. We measured the activity via the 3.3-keV X-rays emitted in the electron capture decay of 41Ca, and the 41Ca abundance was measured by low-energy mass spectrometry. The result, t1/2 = (1.01 ± 0.10) × 105 yr, agrees with the recent ‘geological’ half-life of Klein et al., (1991), t1/2 = (1.03 ± 0.07) × 105 yr, and with the corrected value of Mabuchi et al. (1974), t1/2 = (1.13 ± 0.12) × 105 yr. We recommend the weighted mean of these three measurements, t1/2 = (1.04 ± 0.05) × 105 yr, as the most probable half-life of 41Ca. We also discuss the situation of the radioisotopes, 32Si, 44Ti, 79Se and 126Sn, whose half-lives, though still uncertain, are potentially interesting for future AMS studies and other applications.

181Ir activity was produced via the following heavy-ion reactions: 169Tm (16O,4n)181Ir and 169Tm(19F,7n)181Pt (51 s) decaying to 181Ir. The half-life of 181Ir was found to be 4.90 ± 0.15 min. Singles and coincidence γ-ray measurements were performed using 30–40 cm3 Ge(Li) detectors. X-Ray measurements were carried out using an intrinsic Ge-detector. Additionally the helium jet system was used to study the properties of this isotope. The following γ rays were found to belong to the decay of 181Ir: 19.6, 65.3, 93.8, 107.6, 117.9, 123.5, 184.6, 189.9, 227.0, 231.6, 239.2, 309.0, 318.9, 350.5, 352.8, 375.2, 576.5, 700.1, 871.2, 1182.3, 1192.6, 1347.1, 1381.0, 1528.8, 1545.0, 1565.6, 1593.4, 1639.6, 1646.4, 1652.5, and 1714.9 keV. A tentative decay scheme is proposed for 181Ir, verifying levels in l8lOs that have been obtained by reaction work. The proposed decay scheme as well as spin and parity assignments of some of the 181Os levels are discussed.

Experimental Values

The K shell X-ray photons of Fe, Ag, and Te following the electron capture decay of Co57, Cd109, and I125, respectively, were detected using Si(Li) detector coupled to PC-based 8k multichannel analyzer employing a simple method suggested earlier by our group. The calculated K shell X-ray intensity ratios and vacancy transfer probabilities for these elements are compared with the theoretical values predicted by Scofield and with others’ experimental values obtained via photoionization. It is found that the Κβ to Κα X-ray intensity ratio of Fe is lower by 4.0%, while that of Ag and Te are greater by 7.9% and 19.1%, respectively, from the theoretical values. These deviations may be attributed to the exchange interactions occurring between the 3p–3d shell electrons as well as the recoil effect of the nucleus due to neutrino emission.
