High excitation intensity effects at different pump wave-lengths in PbI2
The emission spectra of PbI2 at 80 K at high intensity of excitation have been investigated by using both a pulsed nitrogen laser and a dye laser as pum** sources. The main experimental observation is that the ...

Stimulated emission in CdS under N2 laser excitation
Optical-gain measurements have been carried out, for the first time, in various samples of CdS excited by a nitrogen laser in the temperature range between 80 K and 300 K. Spontaneous spectra show an additiona...

Photoluminescence of GaSe
Systematic photoluminescence measurements of the p- and n- type GaSe have been carried out in the temperature range between b.2 and 300 K. The main results, reported here, are: 1) direct free exciton emission ...

Two-photon conductivity in ZnS and CdS
Measurements of two-photon conductivity in ZnS(Cu) and CdS single crystals excited by aQ-switched ruby laser are reported. The results show the typical quadratic dependence of two-photon processes. In CdS the pho...

Elastic scattering π++p at 1.0 GeV
The angular distribution π+-p at 1.0 GeV was determined on the basis of l032 events measured in a propane bubble chamber. Comparison is made with data of 820 and 900 MeV and with angular distributions π−+p at sim...
