SUMMARY

Physicists at Florida State University, led by Professor Sam Tabor, have discovered a novel atomic phenomenon involving a cigar-shaped silver atom that ejects two protons simultaneously during radioactive decay. This experiment, conducted at the GSI laboratory in Darmstadt, Germany, involved bombarding nickel foil with calcium atoms, resulting in the formation of silver atoms with a reduced neutron count. The unique shape of the silver nuclei, caused by the neutron deficit, allowed for synchronized proton ejection, challenging existing theories of nuclear decay.

PREREQUISITES
  • Understanding of nuclear physics principles
  • Familiarity with particle collider technology
  • Knowledge of radioactive decay mechanisms
  • Experience with experimental physics methodologies
NEXT STEPS

I haven't had time to digest this, but - http://www.physorg.com/news10263.html

Sam Tabor, a professor of experimental nuclear physics at FSU and director of the university's Superconducting Accelerator Laboratory, recently performed the experiment at the GSI laboratory in Darmstadt, Germany, in collaboration with the international team. In the experiment, a cigar-shaped atom was created using a particle collider. To the scientists' surprise, this atom demonstrated a novel kind of radioactive decay by spitting out two free protons at the same time.

At the GSI lab, Tabor and his colleagues bombarded a thin film of nickel foil with a beam of calcium atoms, causing some nickel and calcium ions to coalesce to form silver atoms with fewer neutrons than normal. Most of these silver atoms decayed conventionally, but a few ejected two protons at once.

The deficit of neutrons in the silver had deformed the nuclei from spheres into fat cigar shapes. In some cases the proton pairs jumped out from the same end of the cigar, at other times from opposite ends, but they were always perfectly synchronized, Tabor said.

The collaborators now are discussing future directions for their research. "However," Tabor said, "we are also performing related research at the Superconducting Accelerator Laboratory right here at FSU.
I wonder how far from Disney World this place is - eh, Zz?

Tallahassee is, unfortunately, rather far from Orlando.

Anyway, if you're citing the same experiment, Astronuc, then... er... isn't this rather "old"? :)
