Positron-electron annihilation momentum transfer to trapped deuterons
AIP ADVANCES(2019)
摘要
The probability of positron annihilation momentum transfer to a trapped deuteron is calculated based on neutron measurements from H-2(d,n)He-3 reactions in deuterated palladium thin films. Deuterium gas loading in Pd thin films creates a high D/Pd fraction at point defects in the metal lattice. Unmoderated positrons from a Na-22 source thermalize and are trapped in the same point defects as deuterium in the Pd thin films. Similar to the Mossbauer effect, an interaction with the surrounding crystal lattice allows for conservation of momentum during electron-positron annihilation energy transfer to the trapped deuteron.
