Coulomb explosion of ionized clusters drives nuclear reactions. This research explores nucleosynthesis using ultraintense lasers and exploding cluster beams for novel nuclear science applications.

Area of Science:

  • Nuclear Physics
  • Laser-Plasma Interactions
  • Materials Science

Background:

  • Ultraintense lasers enable novel nuclear reactions.
  • Cluster beams offer unique targets for laser-driven processes.

Purpose of the Study:

  • To investigate Coulomb explosion of ionized molecular clusters (CH4, NH3, H2O).
  • To explore the potential for driving nuclear reactions and nucleosynthesis in exploding cluster beams.
  • To extend the scope of nuclear reactions initiated by ultraintense laser-hetero-cluster interactions.

Main Methods:

  • Achieving complete electron stripping from clusters using laser intensities >= 10^19 W cm^-2.
  • Utilizing nanodroplets (300-700 A radius) for efficient ionization.
  • Accelerating nuclei to high energies (approx. 30 MeV for heavy nuclei, 3 MeV for protons).
