Flash activation kinetics and photosynthetic unit size for oxygen evolution using 3-nsec light flashes

The flash saturation yield of photosynthetic oxygen evolution in Chlorella is the same for 2-μsec flashes from a xenon flashlamp as for 3-nsec flashes from a dye laser pumped by a nitrogen laser. Following 5 min of darkness, oxygen is produced by the third flash from either source. © 1971.
