An Optically-Pumped Frequency Stable Tunable Maser and Infrared-Microwave Double-Resonance Experiments in Ammonia
Microwave emission attributed to a linear cascade effect has been observed from ('14)NH(,3) optically pumped by a CO(,2) laser. The emission is tunable over the saturated homogeneous linewidth of the ground state sQ(5,4) inversion transition at 22.653 GHz. The circulating power density of the …

Cyclotron resonance in cadmium telluride
"Cyclotron resonance experiments have been performed on single crystals of high purity, n-type CdTe at 4.2°K. A reflection type microwave spectrometer was employed, operating at a frequency of 70 Gc. The mass and the mobility of the carriers, as determined from the resonance spectra, identify the …

… (sites 1, 2 and 3) have been defined. By plasmon resonance experiments, it was shown that the antagonistic monoclonal antibodies against IL-11 (H2, H56 and E33) bind to amino acids located at site 2. The study an description of the mutant H182L, which engages IL-11R-alpha more efficiently, offer …
