Bound states of positrons and large molecules
- 1. ATandT Bell Laboratories, Murray Hill, New Jersey 07974
Description
The lifetime of positrons contained in an electrostatic trap is studied when small quantities of alkanes (i.e., hydrocarbon molecules of the form C/sub n/H2/sub n//sub +2/) are added. As n is increased from 4 to 16, the annihilation rate per molecule is found to increase by a factor of 300 and then to level off. These data are interpreted as evidence for the existence of long-lived resonances and bound states of positrons and neutral molecules, and a model of the formation process is discussed
