论文摘要
经历了甲壳虫释放应变能的脉冲星，可以将其吸收在恒星内部的小区域中，并激发其中的自由超级流体中子。这些中子与周围的涡旋散射可能会取消大量涡流，并有效地减少涡旋线上的固定力。中子散射的这种固定可以产生螃蟹，例如脉冲星和大小的Vela Pulsar的故障。尽管我们在这里讨论了甲壳虫引发的激发，但该提案非常通用，并且同样适用于任何其他来源，这些来源可能会激发自由的超级流体中子，或者可以负责超氟 - 脉冲星内甲壳中中子超氟的正常相变。
Pulsars undergoing crustquake release strain energy, which can be absorbed in a small region inside the inner crust of the star and excite the free superfluid neutrons therein. The scattering of these neutrons with the surrounding pinned vortices may unpin a large number of vortices and effectively reduce the pinning force on vortex lines. Such unpinning by neutron scattering can produce glitches for Crab like pulsars and Vela pulsar of size in the range $\sim 10^{-8} - 10^{-7}$, and $\sim 10^{-9} - 10^{-8}$, respectively. Although we discuss here the crustquake initiated excitation, the proposal is very generic and equally applicable for any other sources, which can excite the free superfluid neutrons, or can be responsible for superfluid - normal phase transition of neutron superfluid in the inner crust of a pulsar.
