“…In addition to the 190 Pt decay, the γ quanta can be emitted in the α decays of other Pt isotopes: (1) when excited levels of the daughter Os nuclei are populated; (2) when the daughter Os isotopes are unstable and further decay with emission of some γ quanta, as in the case of 195 Pt and 198 Pt; in Ref. [81] the T 1/2 limits for these latter decays were determined for the first time.…”

“…Taking into account that the area of the most intensive (I = 82.80%) peak of 192 Ir at 316.5 keV is (619 ± 32) counts (and considering also the different efficiencies of 2.3% at 137 keV 2 and 5.5% at 316 keV), contribution of 192 Ir to the 137 keV peak is 0.6 counts; this does not change the T 1/2 value presented in Eq. (2). Gamma rays with energies close to 137 keV are emitted in some other nuclear processes (see e.g.…”

“…-the cluster decays, where a nuclide decays by emitting nuclides heavier than α particle (from 14 C to 34 Si); about 40 nuclides from 221 Fr to 242 Cm can decay in such a way to isotopes close to 208 Pb ("lead radioactivity") with partial half-lives in the range 10 3 − 10 20 yr [1,2]. The cluster decay was theoretically predicted in 1980 [3] and experimentally observed for the first time in 1984 [4,5].…”

The current status of the experimental searches for rare alpha and beta decays is reviewed. Several interesting observations of alpha and beta decays, previously unseen due to their large half-lives (10 15 − 10 20 yr), have been achieved during the last years thanks to the improvements in the experimental techniques and to the underground locations of experiments that allows to suppress backgrounds. In particular, the list includes first observations of alpha decays of 151 Eu, 180 W (both to the ground state of the daughter nuclei), 190 Pt (to excited state of the daughter nucleus), 209 Bi (to the ground and excited states of the daughter nucleus). The isotope 209 Bi has the longest known half-life of T 1/2 ≈ 10 19 yr relatively to alpha decay. The beta decay of 115 In to the first excited state of 115 Sn (Eexc = 497.334 keV), recently observed for the first time, has the Q β value of only (147 ± 10) eV, which is the lowest Q β value known to-date. Searches and investigations of other rare alpha and beta decays ( 48 Ca, 50 V, 96 Zr, 113 Cd, 123 Te, 178m2 Hf, 180m Ta and others) are also discussed.
