International Team Measures Niobium-94 Neutron Reactions, Explaining Anomalous Molybdenum-94 Abundance in the Solar System

International Team Measures Niobium-94 Neutron Reactions, Explaining Anomalous Molybdenum-94 Abundance in the Solar System

An international team of physicists has, for the first time, conducted a comprehensive study of the interactions between neutrons and the niobium-94 isotope. The findings have been published in Physical Review Letters. The study suggests that the elevated abundance of molybdenum-94 in the primordial material of the solar system can be explained by a series of neutron-involving nuclear reaction processes inside old stars, without requiring the introduction of previously unknown special formation mechanisms. The research was led by Alberto Mengoni, a researcher at the Italian National Institute for Nuclear Physics. The team conducted experiments using the n_TOF facility at CERN, focusing on tracking the interactions between neutrons and niobium-94 atoms. The n_TOF facility is used to...

Consolidating Foundations·Sichuan: Accelerated Localization of Nuclear Medical Equipment Benefits the Public

Consolidating Foundations·Sichuan: Accelerated Localization of Nuclear Medical Equipment Benefits the Public

On August 9, 2026, CCTV's "Morning News" program aired a feature titled "Consolidating Foundations·Sichuan: Accelerated Localization of Nuclear Medical Equipment Benefits the Public," reporting on Jiuyiyuan Company. Founded in February 2017, Sichuan Jiuyiyuan Particle Technology Co., Ltd. is a national high-tech enterprise integrating R&D, production, and services of high-end nuclear medical equipment, committed to providing overall solutions for radiopharmaceuticals. A cyclotron is a device that uses magnetic and electric fields to drive charged particles in a circular motion, repeatedly accelerating them via high-frequency electric fields during their movement. Low- and medium-energy cyclotrons applied in the medical field are devices that produce positron-emitting radionuclides, generating a variety of radionuclides that not only meet clinical PET/CT examination needs but also support the clinical positron drug and new drug development demands of the molecular imaging and precision medicine era. The report noted that core nuclear medicine equipment has long relied on imports, which is a key bottleneck constraining the development of nuclear medicine in China. In 2021, Jiuyiyuan successfully developed the first domestically produced medical cyclotron, breaking foreign technological monopoly. In June this year, the company launched the first domestically produced 30MeV multi-particle medium-to-high-energy cyclotron with fully independent intellectual property rights, with mass production planned for September, achieving internationally advanced product performance.
