Line-shape broadening of an autoionizing state in helium at high XUV intensity

Line-shape broadening of an autoionizing state in helium at high XUV intensity

We study the interaction of intense extreme ultraviolet (XUV) light with the 2s2p doubly excited state in helium. In addition to previously understood energy-level and phase shifts, high XUV intensities may lead to other absorption-line-shape distortions. Here, we report on experimental transient-ab...
