Freeing electrons to better trap them

For the first time, researchers from UNIGE and MBI in Berlin have placed an electron in a dual state -- neither freed nor bound -- thus confirming a hypothesis from the 1970s

The more intense a laser is, the easier should it be to ionise the atom--in other words, to tear the electrons away from…
