The cross-section for bar n annihilation on Fe from 100 to 531 MeV/c was measured by means of a layered absorption detector. The cross-sections are related to the free bar nN annihilation cross-sections by a simple A2/3 scaling law, indicating a surface process.

Abstract
The cross-section for bar n annihilation on Fe from 100 to 531 MeV/c was measured by means of a layered absorption detector. The cross-sections are related to the free bar nN annihilation cross-sections by a simple A2/3 scaling law, indicating a surface process.
