The figure illustrates the experimental setup used to measure neutron leakage spectra from natural lead (nat Pb) slab samples, employing both D-T and D-D neutron sources at the integral experiment ...

World-class particle-accelerator facilities and recent advances in neutron-star observation give physicists a new toolkit for describing nuclear interactions at a wide range of densities. Michigan ...

For most stars, neutron stars and black holes are their final resting places. When a supergiant star runs out of fuel, it expands and then rapidly collapses on itself. This act creates a neutron ...

The 2011 accident at the Fukushima-Daiichi plant in Japan inspired extensive research and analysis that elevated nuclear energy into a standard bearer for safety. It also inspired a number of studies ...

A new experiment conducted at the National Ignition Facility (NIF) assessed the ability of U.S. nuclear weapons to survive encounters with adversary missile defenses and reach their targets. The ...

A groundbreaking collaboration between Los Alamos scientists and Duke University has resurrected a nearly forgotten 1938 experiment that may have quietly sparked the age of fusion energy. Arthur ...

Scientists have replicated a forgotten but crucial experiment that took place in 1938. The first-ever triton-deuterium (colloquially referred to as DT) fusion experiment that was accidentally ...

When the countdown hit zero on September 23, 1992, the desert surface puffed up into the air, as if a giant balloon had inflated it from below. It wasn’t a balloon. Scientists had exploded a nuclear ...

To be useful, clocks need to be consistent. Imagine two spies who synchronize their watches; they rely on them agreeing days or months later, even if one of them must take a frigid hike through arctic ...
