| dc.description | The annihilation rate of room-temperature positrons in low-density gaseous xenon-nitrogen mixtures (n<sub>Xe</sub>5*10<sup>-9</sup> Amagat and n<sub>N2</sub>1*10<sup>-8</sup> Amagat) has been measured. The annihilation rate corresponds to a value of Z<sub>ef</sub>f=40120 for xenon. This is in agreement with measurements in xenon-gas mixtures made at densities nine orders of magnitude greater, but differs significantly from values measured in pure high-density xenon gas. These results indicate that the positrons were not thermalized in the latter case. |
