When a gamma ray passes through matter, the absorption rate is proportional to the thickness of the layer, the density of the material, the absorption cross section of the material, and the energy of ...

The U.S. Naval Research Laboratory (NRL), in partnership with NASA’s Marshall Space Flight Center (MSFC), has developed ...

Every now and again, the night sky lights up with a spectacular explosion that blazes with the most energetic light our Universe can produce. Known as gamma-ray bursts, they can release in a few ...

Key to the success of the technique is the discovery of recoilless gamma ray emission and absorption, now referred to as the 'Mössbauer Effect', after its discoverer Rudolph Mössbauer, who first ...

In October 2022, scientists detected the explosive death of a star 2.4 billion light-years away that was brighter than any ...

I have therefore tried to determine the pulse-height corresponding to those photo-electrons which are created at the absorption of the gamma-rays in the phosphor.
