Source sentences:
text: A free neutron is unstable, decaying to a proton, electron and antineutrino with a mean lifetime of just under 15 minutes (881.5±1.5 s).
text: A free neutron is an unstable particle that decays into a proton, an electron (e-), and an electronic antineutrino (̄ e );
text: Free neutrons are unstable particles which decay naturally into a proton and electron, with a half-life of about 12 minutes.
text: Outside the nucleus, free neutrons are unstable and have a mean lifetime of 880.2±1.0 s (about 14 minutes, 40 seconds); therefore the half-life for this process (which differs from the mean lifetime by a factor of ln(2) = 0.693) is 610.1±0.7 s (about 10 minutes, 10 seconds).
text: Free neutrons are unstable, although they have the longest half-life of any unstable subatomic particle by several orders of magnitude.
text: Free neutrons are unstable, with a half-life of around 13 minutes, but they have important applications (see neutron radiation and neutron scattering).
text: Imagine the consternation of the physicists who found that free neutrons are unstable and decay into pairs of protons and electrons with a half-life of 18 minutes.
text: It's stability is remarkable since the free neutron is unstable, undergoing beta decay with a half life of 10.3 minutes.
text: Free neutrons are unstable, with a half-life of around 13 minutes, but they have important applications (see neutron radiation and neutron scattering).
text: Outside the nucleus, free neutrons are unstable and have a mean lifetime of 880.2±1.0 s (about 14 minutes, 40 seconds).
text: • A free neutron, unlike a free proton, is unstable.
text: Protons also result (along with electrons and antineutrinos) from the radioactive decay of free neutrons, which are unstable.
