In a recent experiment performed
at the Radioactive Isotope Beam Factory
at RIKEN, an international collaboration with scientists from eleven countries, led by scientists of the Instituto de Estructura de la Materia, CSIC (Spain) and the RIKEN Nishina Center (Japan), made a very surprising observation:
High -
energy gamma rays — which are mediated by the electromagnetic force — are emitted in the decay of a certain excited
nucleus — tin 133, in competition with neutron emission, the decay mode mediated by the strong nuclear force.
But
at high energies, the protons tended to escape while the heavier, less mobile
nuclei hung around.
Cosmic rays are atomic
nuclei that zip through space
at the
highest energies observed in nature.
If the company's scientists can scale the technique up to longer times and
higher temperatures, they will reach a stage
at which atomic
nuclei in the gas collide forcefully enough to fuse together, releasing
energy.
Only
at stupendously
high temperatures do the
nuclei acquire enough
energy to overcome their mutual aversion, smash into one another, and fuse.
The use of intermediate size
nuclei is expected to result in intermediate
energy density - not as
high as in earlier runs colliding two beams of gold ions
at the Relativistic Heavy Ion Collider (RHIC), but more than was produced by colliding a beam of gold ions with much lighter deuterons.
Technicolour is very similar to the strong force, which binds quarks together in the
nuclei of atoms, only it operates
at much
higher energies.
Earlier this month, the team working on the experiment, the Payload for Antimatter Matter Exploration and Light -
nuclei Astrophysics, released preliminary data
at the International Conference on
High Energy Physics in Philadelphia, Pennsylvania.
«We looked mostly
at neutrinos created when
high -
energy cosmic rays crash into the
nuclei of nitrogen or oxygen in the Earth's atmosphere.
Through the process of fusion, which is constantly occurring in the sun and other stars,
energy is created when the
nuclei of two lightweight atoms, such as those of hydrogen, combine in plasma
at very
high temperatures.
