The First Neutron Bomb in the U.S. U.S. research on neutron bombs began in 1958 at the University of California's Lawrence Radiation Laboratory under the direction of Edward Teller. News that a neutron bomb was under development was publicly released in the early 1960s. It is thought that...
Electrons are tiny (0.000549 amu), negatively charged particles that are described as orbiting the protons and neutrons that make up an atom's nucleus, in the manner of planets orbiting the sun. This is a rough description at best, however, as advances in quantum physics have led to the co...
Excess lightweight products of slow neutron capture in the photosphere, over the mass range of 25 to 207 amu, confirm the solar mass separation recorded by excess lightweight isotopes in the solar wind, over the mass range of 3 to 136 amu [Solar Abundance of the Elements, Meteoritics, ...
The sample was then pressed into a pellet (400 mg weight and 13 mm in diameter), using a hydraulic press. As a reference, a pellet made of pure polyethylene, with the same diameter and the weight of 360 mg, was prepared. The spectrum was acquired by the accumulation of 3600 scans and...
