我们从理论上研究了在中子星和超新星爆炸中可能遇到的稀薄中子物质中的中子-α波共振的命运。在真空中衰变为中子和α粒子的共振态，在中子费米海中会变成稳定的束缚态，这是因为中子的泡利阻塞效应阻止了衰变过程。这种由泡利阻塞效应辅助的共振到束缚的跃迁可以在异核Feshbach共振附近的量子混合物的冷原子实验中实现。
We theoretically investigate the fate of a neutron-alpha-wave resonance in dilute neutron matter, which may be encountered in neutron stars and supernova explosions. Whileis known as a resonant state that decays to a neutron and an alpha particle in vacuum, this unstable state turns into a stable bound state in the neutron Fermi sea because the decay process is forbidden by the Pauli-blocking effect of neutrons. Such a resonance-to-bound transition assisted by the Pauli-blocking effect can be realized in cold atomic experiments for a quantum mixture near the heteronuclear Feshbach resonance.
