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.

This could excite the nucleus in many different ways, so it was difficult to unravel the vibration phenomena.

With properly selected collision energies, a small portion of the Ni - 66 nuclei thus formed achieve a certain state with a deformed shape which, as measurements showed, proved to be slightly more stable than all other excited states associated with significant deformation.

When the nucleus is excited, its shape may change, but only for an extremely brief moment, after which it returns to its original state.

To excite the voorwerp's glow, the black hole and its surrounding accretion disk, the active galactic nucleus, or AGN, should have had the brightness of about 2.5 trillion suns; its radio emission, however, suggested the AGN emitted the equivalent of a relatively paltry 25,000 suns.
