Abstract
He(Iα)He(IIα) spectra are presented for selenium and tellurium both in the gas phase and as condensed solids. Analysis of the He(IIα) and He(Iα configuration-interaction effects are less important than was previously thought. Measurements of He(IIα)/He(Iα) photoionization cross-section rati. The spectra of the condensed solids indicate that while Te rapidly forms a polycrystalline solid, selenium condenses initially as an amorphous solid wi changes rapidly to give the normal room-temperature spectrum of amorphous selenium. Comparison of the stable amorphous spectrum with that of the polyme contains a large number of cyclic polymers.
