We report on a systematic investigation of the influences of gas pressure,focal position and focusing geometry on high harmonic generation by use of mid-infrared femtosecond laser pulses. We also discuss the spatial characteristics of harmonics under different focusing conditions. By optimizing the parameters,we experimentally observed the generation of 1 kHz,low divergence coherent X-ray beams in the water-window region.

The spectra of highly charged titanium ions produced by the interaction of 120 MeV titanium ions with carbon foil were investigated with the so-called beam-foil technique using the HI-13.tandem accelerator in China institute of atomic energy. Spectral lines emitted from fifty-three excited energy levels were observed in the

The anomaly,or the “V” shape feature,of the anomalous delays of the cros-sing frequencies of 1/2[541]bands observed in Ta isotopes was reproduced very well bythe present calculation based on the mean field theory and was interpreted as the inter-play of the deformation driving effect of the 1/2[541]proton orbit and the pairingmean fields for the first time.
