Abstract：
The nature of the medium lifetime component of positron annihilation in a Teflon (PTFE) polymer has been investigated by usiiig a recently developed Time Selecting γ Energy Spectrometer with and without a magnetic field. It has been assigned to o-Ps quenching annihilation, just the same as the longest lifetime component.
