Muons help hydrogen atoms fuse at room temperature, but efficiency is still limited.
Abstract

Muon-catalyzed fusion (μCF) shrinks atomic orbitals by two orders of magnitude by replacing electrons with muons, allowing deuterium and tritium to fuse at near room temperature. Its dynamics are described as a cycle: muon capture, transfer, formation of a resonant dtμ molecule, and fusion with muon release. The kinetic model enables quantitative assessment of the number of cycles per muon and energy output. The central efficiency limitation — muon sticking to the alpha particle — is potentially surmountable through a combination of double polarization (nuclear and muonic), high-density confinement, electrical muon extraction, and resonant enhancement. Under idealized assumptions, such a four-pronged scheme could increase the number of catalytic cycles from the observed ~150 to over 500, yielding Q>2. On this basis, a hybrid breeder reactor concept μCF-FBR is proposed, where 14.1 MeV fusion neutrons breed 239Pu from 238U in a decoupled mode, offering advantages in reliability, radiation resistance, and use of natural uranium.

Atomic nuclei are wrapped in fluffy electron coats—in such attire, they can't get close enough to embrace. But swap the light coat for a heavy one: a muon, a particle from the standard model, shrinks the cloud by nearly 200 times. Then hydrogen nuclei (deuterium and tritium) fuse on their own at room temperature, giving birth to helium and a burst of energy.

Trouble is, after fusion, the heavy coat sometimes sticks stubbornly to the helium, and the muon is out of the game. Currently, one muon triggers only 150 reactions. But electric fields and special conditions make it slip off, extending the chain to 500 fusions. This yields more energy than what was spent creating the muon.

Muons aren't exotic: every minute, thousands of these particles—born from cosmic rays in the atmosphere—zip through your body.

Such setups could become hybrid reactors: a neutron flux from micro-thermonuclear fusion converts ordinary uranium-238 into plutonium-239, fuel for classic nuclear power plants.

🎯 The natural muon background is used to scan pyramids and find hidden chambers in structures.

Q = \frac{E_{\text{out}}}{E_{\text{in}}}
The ratio of energy output to input. If Q>1, more energy is produced than consumed. The work shows the potential to reach Q>2.
