OBSERVATIONS OF HIGH-DENSITY EFFECTS ON SPECTRAL-LINE SHAPES IN A DENSE (NE LESS-THAN 1018CM-3) Z-PINCH DISCHARGE

The authors report observations of high-density effects on spectral line shapes. Specifically, they present new data on the effects of local plasma polarisation, quasi-molecular interactions, quadrupole potentials and quantum interference effects in dense (ne>1018 cm-3) argon plasmas with only a small number of particles per Debye sphere.
