摘要
研究新放射系衰变纲图.发现在A=235附近,存在着α衰变的瓶颈效应.分析了瓶颈效应的现象和特点,根据原子核结构模型,初步解释了瓶颈效应产生的原因.
μm and 0.532 μm′s SFG in 30° cut LiIO 3 crystal is reported. The highest quantum efficiency is 70% and the energy efficiency of total input light is 17% in Ⅰ type phase match condition. A linear relationship between the total input light and the triplicity frequency light is reportad.
