resonance absorption

[′rez·ən·əns əb‚sȯrp·shən]
(nucleonics)
The absorption of neutrons having a narrow range of energies corresponding to a nuclear resonance level of the absorber in a nuclear reactor.
(quantum mechanics)
The absorption of electromagnetic radiation by a quantum-mechanical system at a characteristic frequency satisfying the Bohr frequency condition. Also known as resonance.
