deuterium nuclei造句

• Many of the deuterium nuclei hit others with enough speed to make them fuse, creating helium and neutrons.
• But deuterium nuclei inside a palladium lattice are further apart than in deuterium gas, and there should be fewer fusion reactions, not more.
• This is why brown dwarfs ( so-called failed stars ) cannot utilize ordinary hydrogen, but they do fuse the small minority of deuterium nuclei.
• In muon-catalyzed fusion there are more fusions because the presence of the muon causes deuterium nuclei to be 207 times closer than in ordinary deuterium gas.
• They also obtained a sample of deuterium, the heavy isotope of hydrogen that had recently been discovered, and bombarded various targets with deuterium nuclei, creating a new class of nuclear reactions.
• Technetium was isolated by Carlo Perrier and Emilio Segr?in 1937, well after Mendeleev s lifetime, from samples of molybdenum that had been bombarded with deuterium nuclei in a cyclotron by Ernest Lawrence.
• In addition, the use of heavy water as a moderator results in the production of small amounts of tritium when the deuterium nuclei in the heavy water absorb neutrons, a very inefficient reaction.
• The first artificial fusion reaction had been achieved by Mark Oliphant in 1932, using two accelerated deuterium nuclei ( each consisting of a single proton bound to a single neutron ) to create a helium-3 nucleus.
• The facility is located about 2 km underground in the former Creighton nickel mine of CVRD Inco in Sudbury, Ontario and was designed to detect solar neutrinos by sensing their interaction with deuterium nuclei and atomic electrons.
• This supposedly happens as hydrogen or deuterium nuclei fuse together to produce heat through a form of nucleus and a proton or an 3 He nucleus and a neutron, have not been detected in a reliable way, leading a vast majority of experts to think that no such fusion is taking place.
