Researchers at Chinese Academy of Sciences have measured the mass of silicon-22, revealing a new proton magic number. This finding provides deeper insight into exotic nuclear structures and nucleon interactions, shedding light on element formation in the Universe.
Scientists use machine learning algorithms to model atomic masses of nuclide chart, complementing research on nuclear structure and astrophysical processes. The approach enables physics-based extrapolations and provides information on 'missing physics'.
Researchers found that ancient stars created elements with atomic masses greater than 260, challenging current knowledge. This discovery provides insight into the process of heavy element formation in stars and could help explain the diversity of elements on Earth.
Researchers from Helmholtz-Zentrum Dresden-Rossendorf are studying near-Earth cosmic explosions to understand their potential impact on the Earth's biosphere. They found that ejected debris can reach our solar system, with some isotopes, such as iron-60 and plutonium-244, potentially coming from supernovae or other galactic events.
Researchers have pushed single-atom vibrational spectroscopy to the level of chemical bonds, enabling precise measurements of point defects in graphene. The study found unique vibrational modes for two types of silicon point defects, with stronger signals for one defect configuration.
Researchers detect radio signal from record-breaking distance galaxy, measuring gas composition and gaining insights into the early universe. The signal was amplified by a factor of 30 using gravitational lensing, allowing scientists to study a previously inaccessible region.
An international team of researchers found that destructive quantum interference suppresses transition between superdeformed and spherical ground states in calcium-40 nuclei. This work may help explain nucleosynthesis processes and the remarkable stability of magic nuclei.
Aalto University researchers demonstrate that each photon is accompanied by an atomic mass density wave, transferring 92% of the total momentum of light in silicon. This resolves the long-standing momentum paradox of light, which had two different values due to neglecting atomic motion with the light pulse.
Researchers at GSI Helmholtz Centre for Heavy Ion Research developed an ion trap device that measures atomic mass with unprecedented accuracy, enabling the discovery of long-lived elements on islands of stability. The team successfully trapped atoms of element 102, nobelium, and measured its atomic mass with a 0.000005% uncertainty.
Researchers have discovered evidence of massive carbon dioxide releases into the atmosphere over a short geological timescale. Fossil records show significant changes in carbon isotope ratios, indicating sudden releases of light carbon isotopes.
