Sentences with phrase «in radioactive nuclei»

«Enriching our knowledge of the structures of highly unstable nuclei and the nucleon - nucleon forces that drive nuclear shell evolution and the appearance or disappearance of the nuclear magic numbers in radioactive nuclei plays an important role in understanding astrophysical processes such as nucleosynthesis in stars,» he adds.

In order for K - 40 to decay by electron capture, there has to be an electron (for the radioactive nucleus) to capture.

Sometimes, as is the case with radioactive isotopes, the number of neutrons present in the nucleus can make the isotope unstable.

In particular, radioactive atomic nuclei are synthesized in the hot, innermost regions during the explosion and can thus serve as probes of the unobservable physical processes that initiate the blasIn particular, radioactive atomic nuclei are synthesized in the hot, innermost regions during the explosion and can thus serve as probes of the unobservable physical processes that initiate the blasin the hot, innermost regions during the explosion and can thus serve as probes of the unobservable physical processes that initiate the blast.

But also new elements are created in the hot ejecta of the explosion, among them radioactive species such as 44Ti (titanium with 22 protons and 22 neutrons in its atomic nuclei) and 56Ni (28/28 neutrons / protons), which decay to stable calcium and iron, respectively.

Since the radioactive atomic nuclei are synthesized in the innermost regions of the supernova, in the very close vicinity of the neutron star, their spatial distribution reflects explosion asymmetries most directly.

The EPR authors described a source, such as a radioactive nucleus, that shot out pairs of particles with the same speed but in opposite directions.

Those nuclei beef up by gobbling neutrons in rapid succession and then quickly change their chemical identities through radioactive decay.

Neutrinos were predicted in 1930 by Wolfgang Pauli, who said they were emitted during radioactive decay within atomic nuclei.

This explains why it took researchers nearly 30 years to catch a first glimpse of neutrinos, although their existence had been first postulated in 1930 to explain an apparent violation of the conservation of energy in the radioactive decay of unstable atomic nuclei known as beta decay.

There are four fundamental forces in the universe: electromagnetism; the strong force, which binds atomic nuclei together; the weak force, which is responsible for radioactive decay; and gravity.

In a project that began last month, researchers will transport antimatter by truck and then use it to study the strange behaviour of rare radioactive nuclei.

In their experiment, a radioactive beam composed of scandium - 55 and titanium - 56 nuclei travelling at around 60 % of the speed of light, was selected and purified by the BigRIPS fragment separator, part of the RIBF.

However, it has recently been shown that the traditional magic numbers, which were once thought to be robust and common for all nuclei, can in fact change in unstable, radioactive nuclei that have a large imbalance of protons and neutrons.

In a radioactive metamorphosis called single beta decay, a neutron (a neutral particle) in the nucleus of an unstable atom spontaneously turns into a proton (a positive particle) and emits an electron and an antineutrino — the antimatter twin of a neutrinIn a radioactive metamorphosis called single beta decay, a neutron (a neutral particle) in the nucleus of an unstable atom spontaneously turns into a proton (a positive particle) and emits an electron and an antineutrino — the antimatter twin of a neutrinin the nucleus of an unstable atom spontaneously turns into a proton (a positive particle) and emits an electron and an antineutrino — the antimatter twin of a neutrino.

In order to determine the mass of the strange hydrogen nucleus as accurately as possible, the nuclear physicists observed the radioactive decay of the nucleus using a combination of several magnetic spectrometers.

Now, however, physicists with Daya Bay report data that support a much simpler explanation: Scientists are merely overestimating the number of neutrinos born from the various radioactive nuclei produced in the fission of one component of standard nuclear fuel.

Antineutrinos are a by - product of the fission in a nuclear reactor, in which an atomic nucleus of a radioactive element such as plutonium splits into lighter elements.

As more and more neutrons pile up in the atom's nucleus, the neutrons undergo a radioactive decay, turning into protons.
