Superintense lasers can break muonic molecular bonds via ion tunneling. This enables laser-controlled nuclear reactions with high precision, using molecules as precursors.

Area of Science:

Atomic and Molecular Physics
Quantum Chemistry
Nuclear Physics

Background:

Muonic molecular ions are exotic systems with unique quantum properties.
Superintense laser fields offer new avenues for manipulating matter at the atomic and molecular level.

Purpose of the Study:

To theoretically investigate the ionization and dissociation of muonic molecular ions in superintense laser fields.
To explore the potential for laser-induced nuclear reactions using muonic molecules.

Main Methods:

Theoretical modeling of muonic molecular ion behavior under intense laser irradiation.
Quantum mechanical calculations of bond breaking via tunneling.
Simulation of ion trajectories and recollision dynamics.

Main Results:

Predicts bond dissociation of muonic ions (e.g., dd mu) at laser intensities > or =10(21) W/cm(2) through barrier tunneling.
Muonic atomic fragment ionization occurs at higher intensities (> or =6 x 10(22) W/cm(2)).
Laser-controlled ion recollision with muonic atoms can trigger nuclear reactions with sub-laser-cycle precision.

Conclusions:

Molecules can serve as precursors for laser-controlled nuclear processes.
Superintense laser fields provide a mechanism for precise control over molecular dissociation and subsequent nuclear reactions.
This research opens possibilities for novel applications in nuclear physics and controlled fusion.
