SUMMARY

The discussion centers on the feasibility of synthesizing gold from iron using particle accelerators, specifically referencing the conditions created in these accelerators that mimic those of a supernova. Participants debated the technological limitations of transforming elements, with one member asserting that such transformations are currently impossible. The conversation highlights the role of particle accelerators, like those at Stanford, in studying fundamental particles rather than facilitating nucleogenesis. Additionally, the discussion mentions historical attempts at transmutation, including Glen Seaborg's work in 1980.

PREREQUISITES
  • Understanding of particle physics and the function of particle accelerators
  • Knowledge of nucleogenesis and element transmutation
  • Familiarity with neutron capture processes
  • Basic principles of nuclear engineering
NEXT STEPS
  • Research the principles of particle accelerators and their applications in modern physics
  • Explore the concept of nucleogenesis and its historical context
  • Investigate neutron capture cross sections and their significance in nuclear reactions
  • Study the work of Glen Seaborg and his contributions to element transmutation
USEFUL FOR

Physicists, nuclear engineers, and anyone interested in the synthesis of elements and the capabilities of particle accelerators.

Hi. On a general discussion forum, we were debating wether gold could be obtained from iron; I argued that this is possible, since we are at the moment recreating, in accelerators, even harsher conditions that those necessary for the creation of gold (i.e. those of a supernova core collapse). A fellow member made the following statement:
Quote:
I think that "syntetical" creation of iron or gold as well as the transformation of iron into gold is technologically impossible and will remain so for a very, very, very long time.

What scientists actually do in those accelerators (e.g. at Stanford) when they refer to "conditions similar to the big-bang" is that they destroy two particles, originally an electron and a positron by accelerating them and have them collide and annihilate each other. The resulting "energy-plasma" is considered to be similar to that shortly after the big-bang...
Is he correct? Thanks.

Hg-196 + neutron > Au-197
Alchemists of old just needed a simple neutron. Cheers, Jim
 
Glen Seaborg transmuted Lead into Gold in 1980. The purpose of particle accelerators is not nucleogenesis, but rather examining the internal structure of smaller things, like individual protons, neutrons, quarks, and the like.

Huh, nifty. I wonder what the cross section for neutron capture of Hg 196 would be?
 
Thanks a lot guys! You have been very helpfull.
