چکیده
|
Development of a doppler broadening positron spectroscopy setup is reported. the setup consists of an hpge detector with energy resolution of 2.1 kev at 411.8 kev in coincidence with a nai detector. the stability of the electronic devices was extensively studied. finally, the relative positron-electron momentum distribution for commercial al was measured. the comparison between our data and other’s data reveals a very good agreement.
