Recent observations of molecular positronium (Ps2) were based on a correlation between changes in positronium (Ps) lifetime spectra associated with the density of an incident positron beam and the population of a positronium (or positron) surface sta

It is well known that ortho-positronium (ortho-Ps) atoms are emitted with high efficiency from various porous materials following the implantation of positrons. Since the ortho-Ps lifetime in a mesoporous material may be a substantial fraction of the

Long-lived |m|=1 positronium (Ps) atoms are produced in vacuum when high density bursts of positrons with net polarization p0 are implanted into a porous silica film in a 2.3 T magnetic field. We observe a decrease in the |m|=1 population as the dens

We have measured the kinetic energy of positronium (Ps) atoms emitted into a vacuum from a porous silica film subsequent to positron bombardment, via the Doppler spread of the linewidth of the Ps ${1}^{3}S$-${2}^{3}P$ transition. We find that the dee

The use of rotating electric fields to control plasmas has found numerous applications in the manipulation and storage of antimatter. When used in strong magnetic fields plasma heating caused by the applied field is mitigated by cyclotron cooling, le

The production of molecular positronium and the existence of excited states of this molecule make it natural to consider performing laser spectroscopy on this four-particle matter-antimatter system. We report here progress towards this goal, includin
