Experiments on the production of a highly dispersible calcium carbonate. ('Experimental section' only) [Translation from: Szklo i Ceramiki 30, 133-136, 1979]

This short translation summarises experiments on the production of a highly dispersible precipitate of calcium carbonate. The translation covers the 'Experimental section' (of the original larger paper) only.

133-W pulsed fiber amplifier with large-mode-area fiber

A master-oscillator fiber power amplifier (MOPA) system with a 4-m-long Yb3+-doped homemade large mode area (LMA) double-clad fiber is reported. The system emits up to 133.8 W of amplified radiation at a wavelength of 1064 nm and a repetition rate of 100 kHz, limited only by the available pump power. Peak power of 300 kW at 20 kHz with a pulse duration of 15 ns is obtained. (c) 2006 Society of Photo-Optical Instrumentation Engineers.

47 MeV/u ~(12)C与~(133)Cs反应中碘同位素产生截面的Q_(gg)依赖关系

用47 MeV/u 12C离子轰击133Cs靶,应用放射化学分离技术和离线γ射线谱学,得到碘同位素的产生截面。丰中子碘同位素的独立产生截面指数地依赖于Qgg值,而缺中子碘同位素的独立产生截面则偏离这一直线关系。这一事实可对在深部非弹转移过程中产生丰中子碘同位素予以解释。
