The decay of quadrupole-octupole $1^-$ states in $^{40}$Ca and $^{140}$Ce

, 2016
Background: Two-phonon excitations originating from the coupling of two collective one-phonon states are of great interest in nuclear structure physics.

Strengths of the resonances at 436, 479, 639, 661, and 1279 keV in the $^{22}$Ne(p,$\gamma$)$^{23}$Na reaction

, 2015
The $^{22}$Ne(p,$\gamma$)$^{23}$Na reaction is included in the neon-sodium cycle of hydrogen burning. A number of narrow resonances in the Gamow window dominates the thermonuclear reaction rate. Several resonance strengths are only poorly known.

Experimental Determination of L Shell Fluorescence Yields and Coster–Kronig Transition Probabilities of Platinum

X-Ray Spectrometry, Volume 55, Issue 1, Page 190-201, January/February 2026.
ABSTRACT An accurate database of atomic fundamental parameters (FPs) is crucial for quantitative material analysis based on x‐ray fluorescence (XRF). Given the wide range of applications and the limited reliability of existing experimental FPs for the L subshells of platinum, we determined its partial L fluorescence yields and Coster–Kronig transition ...

An Extended Amplitude Range Readout Circuit for Charged Particle Detection–BEAR 2

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Charge sensitive amplifiers (CSA) form the first stage of most detector readout circuits. The operating range of the readout circuits depends on the saturation limits of the Charge sensitive amplifiers, thereby limiting the range of the detector system as well. A number of methods have been introduced to extend the dynamic range of the readout

Experimental demonstration of an isotope-sensitive warhead verification technique using nuclear resonance fluorescence

, 2018
Future nuclear arms reduction efforts will require technologies to verify that warheads slated for dismantlement are authentic without revealing any sensitive weapons design information to international inspectors. Despite several decades of research, no

Gaia: segmented germanium detector for high‐energy X‐ray fluorescence and spectroscopic imaging

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 91-97, January 2026.
We present Gaia, a cryogenically cooled monolithic array of 96 high‐purity germanium pixel detectors integrated with a custom low‐noise application‐specific integrated circuit and a field‐programmable gate array‐based data acquisition system. The system achieves an average energy resolution of 711 eV at 122 keV and 253 eV at 5.89 keV, and serves as the

Search for double beta decay of $^{136}$Ce and $^{138}$Ce with HPGe gamma detector

, 2014
Search for double $\beta$ decay of $^{136}$Ce and $^{138}$Ce was realized with 732 g of deeply purified cerium oxide sample measured over 1900 h with the help of an ultra-low background HPGe $\gamma$ detector with a volume of 465 cm$^3$ at the STELLA ...

Does an Increase in Number of Deep Burrowing Earthworms Enhance Subsurface Nutrient Losses?

European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.
ABSTRACT Deep burrowing earthworms Lumbricus terrestris can be abundant along subdrain trenches, creating macropores that may serve as preferential flow paths for particles and agrochemicals to subdrains. We examined L. terrestris abundance, subdrain water discharge, and nutrient loss trends during 2002–2022 in an arable no‐till clay soil with an ...
