Research news on Gamma-ray techniques

Gamma-ray techniques encompass experimental and analytical methods that utilize high-energy photons, typically above 100 keV, to probe nuclear structure, material composition, and high-energy processes. These techniques include gamma-ray spectroscopy for resolving discrete nuclear energy levels via high-purity germanium or scintillation detectors, gamma radiography and tomography for non-destructive internal imaging based on differential attenuation, and activation analysis where induced radioactivity quantifies elemental concentrations. They rely on well-characterized interactions such as photoelectric absorption, Compton scattering, and pair production, and often require precise energy calibration, shielding, coincidence measurements, and advanced signal processing to achieve high resolution, sensitivity, and isotopic selectivity.

Gamma rays quickly toughen nitrogen‑fixing bacteria

Heat-resilient biofertilizers could help crops cope with rising temperatures but engineering them has been slow and uncertain. A new study at the National Institutes for Quantum Science and Technology (QST) shows that pairing ...

Novel design for fast, sensitive high-energy photon detector

Prof. Long Shibing and his team from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) have proposed a novel strategy for a high-energy photon detector with high sensitivity ...

Hunting for elusive tetraneutrons with thermal fission

The possible emission rate of particle-stable tetraneutron, a four-neutron system whose existence has been long debated within the scientific community, has been investigated by researchers from Tokyo Tech. They looked into ...
