“…By contrast, the dynamics of hard non-deformable grains is essentially related to geometry: elementary plastic events are rather identified as the rapid formation of force chains followed by a slow zig-zag instability of these structures [32]. Non-locality can then be related to soft modes, by essence spread in space, prescribing the cooperative motion of the particles [33]. In this geometrical picture, the relevant state parameter would rather be the mean number of contacts per particle Z or the volume fraction φ [34].…”

Nonlocal Rheology of Granular Flows across Yield Conditions

et al. 2013

The rheology of dense granular flows is studied numerically in a shear cell controlled at constant pressure and shear stress, confined between two granular shear flows. We show that a liquid state can be achieved even far below the yield stress, whose flow can be described with the same rheology as above the yield stress. A nonlocal constitutive relation is derived from dimensional analysis through a gradient expansion and calibrated using the spatial relaxation of velocity profiles observed under homogeneous stresses. Both for frictional and frictionless grains, the relaxation length is found to diverge as the inverse square root of the distance to the yield point, on both sides of that point.

“…Taking into account that the energy of the 115 Sn first excited level was known as E exc = (497.334 ± 0.022) keV [255], the energy release in the decay 115 In → 115 Sn * was equal to Q * β = (155 ± 24) eV, that is the lowest known Q β value among the observed β decays (the next one is Q β = (2.467 ± 0.002) keV for 187 Re [63]). The observation [256] was confirmed in measurements of In sample (2566 g) at the HADES underground laboratory with 3 HPGe detectors; slightly more precise values of half-life were obtained: T 1/2 = (4.1 ± 0.6) × 10 20 yr [197] and T 1/2 = (4.3 ± 0.5) × 10 20 yr [198].…”

Experimental searches for rare alpha and beta decays

et al. 2019

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.

“…115 In → 115 Sn * . Decay of 115 In to the first excited level of 115 Sn (E exc = 497.334 (22) keV) was at the first time observed in [28] and further confirmed in [29,30]. Precise measurements of the atomic mass difference between 115 In and 115 Sn, ∆M A = 497.489 ± 0.010 keV [31], allowed to conclude that 115 In → 115 Sn * is the β decay with the lowest known Q * β value of only 155 ± 24 eV.…”

Current status of experimental investigations of rare single beta decays (48Ca, 50V, 96Zr, 113Cd, 113mCd, 115In, 123Te, 180mTa, 222Rn) is reviewed. Nuclei which decay through single beta decay very often constitute backgrounds in studies of rare effects like double beta decay, solar neutrinos or dark matter. Summary of correction factors used in description of forbidden beta decays is also briefly given.Comment: 4 pages, contribution to the MEDEX'2017 conference, one more acknowledgment adde
