Low‐Cost Monitoring of Energetic Particle Precipitation: Weather Balloon‐Borne Timepix Measurements During the May 2024 Superstorm

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Understanding energetic electron precipitation is crucial for accurate space weather modeling and forecasting, impacting the Earth's upper atmosphere and human infrastructure. This study presents a low‐cost, low‐mass, and low‐power solution for high‐fidelity analysis of electron precipitation events by measuring the resulting bremsstrahlung X ...

Electroweak Radiative Corrections to Muon Capture

, 2007
Electroweak radiative corrections to muon capture on nuclei are computed and found to be sizable. They enhance the capture rates for hydrogen and helium by 2.8% and 3.0% respectively.

Structural and magnetic properties of β‐Li2IrO3 after grazing‐angle focused ion beam thinning

Acta Crystallographica Section B, Volume 81, Issue 2, Page 202-207, April 2025.
A minimally invasive use of a focused ion beam at grazing incidence can reduce the size of bulk crystals without jeopardizing the structural and electronic order parameters.Manipulating the size and orientation of quantum materials is often used to tune emergent phenomena, but precise control of these parameters is also necessary from an experimental ...

Value of the Axial-Vector Coupling Strength in β and ββ Decays: A Review

Frontiers in Physics, 2017
In this review the quenching of the weak axial-vector coupling strength, gA, is discussed in nuclear β and double-β decays. On one hand, the nuclear-medium and nuclear many-body effects are separated, and on the other hand the quenching is discussed from

Muon capture in 40Ca

Physics Letters B, 1967
Abstract The total muon capture rate in 40Ca leading to 40K is calculated in the hole-particle model. For the Goldberger-Treiman value of gP/gA, the result is only slightly larger than the available experimental value. The influence of second class terms is then considered and the variation of total rate with respect to tensor coupling constant is ...

Muon capture in 28Si and

Physics Letters B, 1997
Abstract Negative muon capture in 28Si was used to determine the angular correlation between the neutrino and the 1229 keV γ-ray from the de-excitation of the 2201 keV 1+ level in 28Al. To suppress backgrounds in the HPGe detectors, a coincidence was required with the 942 keV γ-ray in the de-excitation cascade detected in a NaI array.

Determination of Residual Stress in Additively Manufactured 316L Stainless Steel Benchmark Parts Through Synchrotron X‐Ray Diffraction and Neutron Diffraction

Strain, Volume 61, Issue 2, April 2025.
ABSTRACT Additive manufacturing (AM) of parts is typically associated with the generation of high residual stresses because of repeated exposure to high thermal gradients. Non‐destructive means of mapping the residual stresses are required for optimising these processes and/or mitigating such stresses by thermal treatments.

On the muon capture in 6Li

Physics Letters B, 1969
Abstract The muon capture rate in 6 Li leading to the ground state of 6 He is calculated from the magnetic form factor of 6 Li, using projected Hartree-Fock wave functions.

On Muon Capture in Heavy Nuclei [PDF]

Il Nuovo Cimento, 1964
The theory of the Primakoff plot is developed in a simple way. Corrections advocated byKlein andWolfenstein are shown to be absent when reasonable correlation functions, such as those of the ideal Fermi gas, are used. However, development of the gas model throws doubt on the accuracy of the theory.

Denudation rates and Holocene sediment storage dynamics inferred from in situ 14C concentrations in the Feshie basin, Scotland

Earth Surface Processes and Landforms, Volume 50, Issue 4, 30 March 2025.
Inferred catchment‐averaged denudation rates in post‐glacial landscapes do not always reflect true ‘basin‐wide’ denudation rates, and instead represent a mixture of sediment sourced from paraglacial deposits and ‘background’ hillslopes. Our results highlight the role of the glacial legacy on landscape evolution.
