For decades, scientists believed that lead-208, a "doubly magic" and highly stable atomic nucleus, was perfectly spherical.

For that, you need something like this gamma-ray spectroscope ... [mihai.cuciuc] took inspiration for the Pomelo from this DIY spectrometer as well as the CosmicPi.

ESA’s Integral observed space for 22 years, uncovering gamma-ray bursts, black holes, and gravitational waves.

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

The lead isotope known as lead-208 was considered a “double magic” atom because of its subatomic particles—until the reveal of something completely unexpected. It was supposed to be a physics fairy ...

Using the state-of-the-art GRETINA gamma-ray spectrometer at Argonne National Laboratory in Illinois, USA, scientists bombarded lead atoms with high-speed particle beams accelerated to 10% of the ...

We don’t know why [stoppi71] needs to do gamma spectroscopy. We only know that ... You also need a scintillation crystal to convert the gamma rays to visible light for the tube to pick up.

Using the state-of-the-art GRETINA gamma-ray spectrometer at Argonne National Laboratory in Illinois, U.S., scientists bombarded lead atoms with high-speed particle beams accelerated to 10% of the ...

These two factors limit the number of isotopes that can be used successfully for Mössbauer spectroscopy. The most used is 57 Fe, which has both a very low energy gamma-ray and long-lived excited state ...
