attosecond

"They built up nice little pictures, " says David Villeneuve, program leader of attosecond science at the National Research Council of Canada in Ottawa..“他们制作了漂亮的小图片，”David Villeneuve说，他是在加拿大渥太华的国家研究理事会的阿托秒科学的项目领导。

The attosecond X-ray pulses strong field electronic dynamics of both bound and continuum electrons can be characterized by measuring the high energy photoelectron spectra yielded by recollision..通过测量碰撞复合过程中的高能电子的辐射谱可以重构阿秒X光脉冲以及探测强场下束缚态和连续态电子动力学。
