    Investigating the Shallow to Mid-Depth (>100–300 °C) Continental Crust Evolution with (U-Th)/He Thermochronology: A Review by Cécile Gautheron, Mathias Hueck, Sébastien Ternois, Beatrix Heller, Stéphane Schwartz, Philippe Sarda, Laurent Tassan-Got

    Published 2022-04-01
    “…Among them is the (U-Th)/He dating method, which is based on the production and retention, within a crystal structure, of radiogenic <sup>4</sup>He atoms associated with the alpha decay of U, Th and Sm nuclei. While apatite has been the main target of (U-Th)/He studies focusing on exhumation and burial processes in the upper levels of the continental crust (~50–120 °C), the development of (U-Th)/He methods for typical phases of igneous and metamorphic rocks (e.g., zircon and titanite) or mafic and ultramafic rocks (e.g., magnetite) over the last two decades has opened up a myriad of geological applications at higher temperatures (>100–300 °C). …”

    High helium reservoirs in the Four Corners area of the Colorado Plateau, USA by Halford, DT, Karolyte, R, Barry, PH, Whyte, CJ, Darrah, TH, Cuzella, JJ, Sonnenberg, SA, Ballentine, CJ

    Published 2022
    “…Radiogenic 4He is naturally produced in Earth's crust due to alpha decay of Uranium (U) and Thorium (Th). Helium has unique thermodynamic properties required for the medical imaging industry, aerospace and other fields of high-tech manufacturing, and currently is in increasingly high demand. …”

    Control on (U-234/U-238) in lake water: A study in the Dry Valleys of Antarctica by Henderson, G, Hall, B, Smith, A, Robinson, L

    Published 2006
    “…The (234U/238U) ratio in surface waters is generally higher than secular equilibrium due to nuclide recoil during alpha-decay of 238U. The size of the deviation from secular equilibrium contains information about the environment in which the water is found. …”

    Structure of the prompt neutron multiplicity distribution in the spontaneous fission of 256Rf by A.V. Isaev, R.S. Mukhin, A.V. Andreev, Z. Asfari, M.L. Chelnokov, V.I. Chepigin, H.M. Devaraja, O. Dorvaux, B. Gall, K. Hauschild, I.N. Izosimov, A.A. Kuznetsova, A. Lopez-Martens, O.N. Malyshev, A.G. Popeko, Yu.A. Popov, A. Rahmatinejad, B. Sailaubekov, T.M. Shneidman, E.A. Sokol, A.I. Svirikhin, M.S. Tezekbayeva, A.V. Yeremin, N.I. Zamyatin

    Published 2023-08-01
    “…The average number of neutrons of ν‾=4.30±0.17 and variance of σν2=3.2 from the prompt neutron multiplicity distribution were obtained. The alpha decay branching ratio of bα=0.003−0.003+0.005 and the half-life of T1/2=(6.7±0.2) ms of the isotope were determined. …”

    Superradiance in alpha clustered mirror nuclei by Alexander Volya, Marina Barbui, Vladilen Z. Goldberg, Grigory V. Rogachev

    Published 2022-12-01
    “…No physical system is truly isolated, and the influence of the external world on structure and dynamics of quantum many-body systems is not well explored. Alpha decays in mirror nuclei studied in this work demonstrate significant restructuring of quantum states due to decay.…”

    The CRESST-III low-mass WIMP detector by Angloher, G, Bento, A, Bucci, C, Canonica, L, Defay, X, Erb, A, von Feilitzsch, F, Ferreiro Iachellini, N, Gorla, P, Gütlein, A, Hauff, D, Jochum, J, Kiefer, M, Kluck, H, Kraus, H, Lanfranchi, J, Loebell, J, Münster, A, Pagliarone, C, Petricca, F, Potzel, W, Pröbst, F, Reindl, F, Schäffner, K, Schieck, J, Schönert, S, Seidel, W, Stodolsky, L, Strandhagen, C, Strauss, R, Tanzke, A, Trinh Thi, H, Türkoğlu, C, Uffinger, M, Ulrich, A, Usherov, I, Wawoczny, S, Willers, M, Wüstrich, M, Zöller, A

    Published 2016
    “…A fully-scintillating inner detector housing is realised which efficiently rejects events from surface alpha decays. The CaWO4 sticks holding the target crystal are also operated as calorimeters to discriminate all possible artefacts related to the support structure. …”

    SUPERFACT: A Model Fuel for Studying the Evolution of the Microstructure of Spent Nuclear Fuel during Storage/Disposal by Thierry Wiss, Oliver Dieste, Emanuele De Bona, Alessandro Benedetti, Vincenzo Rondinella, Rudy Konings

    Published 2021-10-01
    “…Due to the high content in rather short-lived alpha-decaying actinides, both the archive, but also the irradiated fuels, cumulated an alpha dose during a laboratory time scale, which is comparable to that of standard LWR fuels during centuries/millenaries of storage. …”

    Background rejection in the DMTPC dark matter search using charge signals by Ahlen, S., Inglis, A., Tomita, H., Wellenstein, H., Dujmic, Denis, Battat, James, Deaconu, Cosmin, Monroe, Jocelyn, Sciolla, Gabriella, Fisher, Peter H, Kaboth, Asher Cunningham, Yamamoto, R. K., Henderson, Shawn Wesley, Lopez, Jeremy Paul

    Published 2016
    “…A combined charge and CCD analysis yields a background-limited upper limit of 1.1 × 10[superscript −5] (90% confidence level) for the rejection of γγ and electron events. Backgrounds from alpha decays from the field cage are eliminated by introducing a veto electrode that surrounds the sensitive region in the TPC. …”
