A photoionization-confined shell—a dense, shocked layer separating the neutral inner wind from the ionized outer wind—forms closer to the star. We identify this with the recently discovered ...

Researchers at East China Normal University and Queen's University Belfast recently built on the RABBITT technique to distinctly measure individual contributions in photoionization. Their paper ...

Haiyang Li from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has discovered a new competition mechanism in vacuum ultraviolet photoionization of ...

Photoionization detector-equipped instruments are increasingly being used as the detection technique of choice in these applications. OSHA's permissible exposure limits (PELs) are designed to ...

Photoionization detectors (PIDs) are gas detection technology that can help businesses address this risk from the start, maintaining the highest level of short- and long-term safety for workers.
