Superheavy elements: a crossroads.

G T Seaborg, W Loveland, D J Morrissey

    Science (New York, N.Y.)
    |February 23, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Synthesizing superheavy elements using complete fusion reactions fails due to low survival rates of precursors or incomplete fusion. Future attempts will explore complete fusion and deep inelastic transfer reactions.

    Area of Science:

    • Nuclear Physics
    • Heavy Element Synthesis

    Background:

    • Complete fusion reactions are a primary method for synthesizing superheavy elements.
    • Low survival probabilities of superheavy nuclei and incomplete fusion hinder successful synthesis.

    Purpose of the Study:

    • To explain the reasons for the failure in synthesizing superheavy elements via complete fusion reactions.
    • To discuss future strategies for superheavy element synthesis.

    Main Methods:

    • Analysis of survival probabilities of superheavy precursors.
    • Evaluation of complete fusion and deep inelastic transfer reaction mechanisms.

    Main Results:

    • The low survival probability of superheavy precursors is a key factor limiting synthesis.

  • Incomplete fusion can also prevent the formation of superheavy elements.
  • Results suggest alternative reaction pathways are needed.

    • Conclusions:

    • Complete fusion reactions are often insufficient for superheavy element synthesis due to inherent nuclear instability.
    • Future research should focus on optimizing reaction conditions and exploring alternative reaction types like deep inelastic transfer.
