Measurement of the double- $$\varvec{\beta }$$ β decay of $$\varvec{^{150}}$$ 150 Nd to the 0 $$\varvec{^+_1}$$ 1 + excited state of $$\varvec{^{150}}$$ 150 Sm in NEMO-3

European Physical Journal C: Particles and Fields, 2023
The NEMO-3 results for the double- $$\beta $$ β decay of $$^{150}$$ 150 Nd to the 0 $$^+_1$$ 1 + and 2 $$^+_1$$ 1 + excited states of $$^{150}$$ 150 Sm are reported. The data recorded during 5.25 year with 36.6 g of the isotope $$^{150}$$ 150 Nd are used

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

Meteoritics &Planetary Science, EarlyView.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Chemical Variation of Tourmaline and Source of Hydrothermal Solutions in Nezam Abad W-(Sn) Ore Deposit, Sanandaj-Sirjan Zone, West-Central Iran [PDF]

Journal of Sciences, Islamic Republic of Iran, 2009
Tourmalinization characterizes the most pervasive alteration type in the Nezam Abad ore deposit, west-central Iran. It delineates high-temperature centers of mineralization and together with quartz and cassiterite form inner parts of the alteration halo.

Archaean and Proterozoic diamond growth from contrasting styles of large-scale magmatism [PDF]

, 2017
Precise dating of diamond growth is required to understand the interior workings of the early Earth and the deep carbon cycle. Here we report Sm-Nd isotope data from 26 individual garnet inclusions from 26 harzburgitic diamonds from Venetia, South Africa.

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins

Meteoritics &Planetary Science, EarlyView.
Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...
