Abstract ： The feasibility of pair produced positron annihilation technique, which provides the electron momentum information of materials by analyzing the spectrum from pair produced positron annihilation, is studied. In this technique the positrons produced by low energy r-ray in a sample are moderated and annihilated and the Doppler broadening annihilation spectrum is measured and analyzed.
