Abstract Generation of attosecond bunches of energetic electrons offers significant potential from ultrafast physics to novel radiation sources. However. it is still a great challenge to stably produce such electron beams with lasers. since the typical subfemtosecond electron bunches from laser-plasma interactions either carry low beam charge. https://qnvzwdpf45e9sh.timeblog.net/70688066/social-conditions-and-maternal-conducts-in-the-prevention-and-management-of-infantile-diarrhea
