超导环对中子的非弹性散射

Inelastic scattering of neutrons by superconducting rings

A. I. Agafonov

摘要:

考虑中子磁矩与超导电流产生的磁场的相互作用,从理论上导出了中子被超导环非弹性磁散射的微分截面。在这个散射过程中,中子的动能离散地增加,而环中捕获的磁通量量子数则相应地减少。本文定量计算了薄膜厚度为$d<λ$($λ$为穿透深度)的Ⅱ型超导体薄膜环对冷中子的散射截面。

英文摘要:

The differential cross section for the inelastic magnetic scattering of neutrons by superconducting rings is derived theoretically taking account of the interaction of the neutron magnetic moment with magnetic field created by the superconducting current. In this scattering process the neutron kinetic energy increases discretely and, respectively, the number of the magnetic flux quanta trapped in the ring, reduces. Quantitative calculations of the scattering cross section for cold neutrons is carried out for thin film rings from type-II superconductors with the film thickness $d<λ$($λ$ is the penetration depth).
