Nonlinear density dependence of the positron decay rate in helium

Research output: Contribution to journalComment/debateScientificpeer-review

Abstract

The decay rate of thermalized positrons in helium is calculated as a function of the fluid density, incorporating the multiple scattering of the positron off the atoms. The obtained nonlinearity agrees with experimental data outside the self-trapping region.
