Mechanical Detection of Nuclear Decays

Area of Science:

• Nuclear Physics
• Quantum Mechanics
• Optomechanics

Background:

• Traditional methods struggle to detect neutral particles emitted during nuclear decays.
• Detecting the recoil of massive particles from nuclear decay is challenging.

Purpose of the Study:

• To develop a novel method for detecting individual nuclear alpha decays.
• To leverage levitated optomechanics for high-sensitivity nuclear decay detection.

Main Methods:

• Utilizing levitated optomechanics to precisely control and measure the motion of optically trapped, micron-sized particles.
• Detecting the mechanical recoil of the entire particle caused by the embedded decaying nuclei.
• Correlating particle recoil with coincident changes in net charge to identify decays.

Main Results:

• Successfully detected individual nuclear alpha decays via particle recoil.
• Achieved background levels at the micro-Becquerel level.
• Demonstrated sensitivity to neutral particles emitted during decay.

Conclusions:

• Levitated optomechanics offers a new pathway for detecting nuclear decays with unprecedented sensitivity.
• This technique has potential applications in nuclear forensics, dark matter, and neutrino physics.
