How a Lithium Atom Transforms into a Hydrogen Isotope

Click For Summary

Discussion Overview

The discussion revolves around the transformation of lithium atoms into hydrogen isotopes, particularly in the context of nuclear fusion and the mechanics of hydrogen bombs. Participants explore the processes involved in fusion reactions, the role of lithium, and the conditions necessary for these transformations to occur.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant describes the initial process of a hydrogen bomb, noting that conventional explosives like TNT are used to initiate fission, which then generates the heat required for fusion.
  • Another participant questions how lithium can transform directly into a hydrogen isotope, specifically tritium, when bombarded by electrons.
  • A participant emphasizes the necessity of pressure and heat for fusion, highlighting that mere suspension of an A-bomb within fusion fuel is insufficient for a reaction to occur.
  • Detailed reactions involving lithium and deuterium are presented, including various products and the energy released (Q values) from these reactions, suggesting multiple pathways for lithium's transformation.
  • It is noted that the second reaction involving lithium applies specifically to fast neutrons, which are produced in fission or D + T reactions, and that slow neutrons do not arise from these processes.

Areas of Agreement / Disagreement

Participants express differing views on the mechanisms of lithium transformation and the conditions necessary for fusion, indicating that multiple competing perspectives remain without a consensus.

Contextual Notes

Some limitations include the dependence on specific conditions for fusion reactions, such as neutron speed and the configuration of the fission trigger and fusion chamber, which are not fully resolved in the discussion.

From what I gather a hydrogen bomb works by exploding a conventional explosive such as TNT which propells fissile Uranium or Plutonium particles at each other which causes fission and this fission causes enough heat to start fusion.

Then I hear lithium is bombarded with by an electrons which cause it to transform into tritium. My question is how does a lithium atom transform directly into a hydrogen isotope??

2D + 6Li produces the following possible results

3He + 4He + 01n, Q = 2.56 or 1.8 MeV

2 4He, Q = 22.4 MeV

1H + 7Li, Q = 5.0 MeV

7Be + 01n, Q = 3.4 MeV



2D + 7Li produces the following possible results

8Be + 01n, Q = 15.0 MeV

2 4He + 01n, Q = 15.1 MeV

Where Q is the energy (as kinetic energy of the products) released from the reaction.


The second reaction cited by Hurkyl applies to fast neutrons, which would be produced by a fission reaction or D + T reaction. Thermal or slow neutrons are not produced in fission or fusion reactions.

01n (fast) + 7Li -> 3H + 4He + 01n (slow)


Simply suspending an A-bomb inside a vessel of fusion fuel will not work.
The fission trigger and fusion reaction chamber are specially configured, of course.
