ABSTRACT Our modern laboratory of nuclear physics has expanded to encompass parts of the universe, or at least our Galaxy. Gamma rays emitted by the decays of radioactive nuclei testify to the ...

In addition, the group found that the gamma-ray line evolves as a power-law function of time, providing critical clues to unveil the mystery of the line. The study was published in Science China ...

and they activate interstellar matter to emit spectral emission lines of X-rays and gamma rays specific to the elements. In this research, we will establish an imaging method to visualize line X-ray ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

That gamma rays under certain experimental conditions appear to become less penetrating as they pass through matter was shown by Dr. Gray in 1913. Recently it has been shown by me (Phil.

Caption The top panel shows the power-law evolution of the energy of gamma-ray line (blue) detected in GRB 221009A, while the prompt emission (black) and afterglow (gray) of this burst are plotted ...

Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...

This database offers a variety of tables for all natural elements and includes the following data: isotopic composition, thermal radiative cross section (total and partial), Westcott g-factors, energy ...

is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma ray emissions. Inaccurate and incomplete data ...
