1. Delayed neutrons play an important role in the timing of these oscillations.2. The neutrons are usually classified in 6 delayed neutron groups. 3. Delayed neutrons are associated with the beta decay of the fission products.4. These neutron-emitting fission fragments are called delayed neutron precursor atoms. 5. Delayed neutron analysis is becoming increasingly useful for these studies.6. If these delayed neutrons are captured without producing fissions, they produce heat as well. 7. Delayed neutron analysis can be used for accurate screening of various materials for fissile content.8. The lifetime of delayed neutrons ranges from fractions of seconds to almost 100 seconds after fission. 9. These neutron-emitting fission fragments are called " delayed neutron precursor atoms ". 10. Hence the neutron that originates from the precursor's decay is termed a delayed neutron .
