Neutrons are subatomic particles that are typically stable when they’re inside an atom’s nucleus.
Robert Pattie, a physicist at East Tennessee State University in Johnson City who did not contribute to the new paper, called the new results “a neat experiment.” Multiple measurements of a neutron's lifetime But it shows it’s possible that future space-based measurements might be precise enough to help answer the question of how long neutrons survive. This new measurement - based on data captured near the moon - is less precise than the lab measurements, and it does not clarify if either of the two lab results is correct.
In a new study, researchers for the second time have measured the neutron lifetime in a setting far outside the lab - space. (Inside Science) - Scientists have been trying to measure the lifetime of a neutron outside an atomic nucleus for decades, and for the last 15 years, two types of laboratory experiments have provided different answers.
