Fission Fragment Energy Deposition Efficiency (open access)

Fission Fragment Energy Deposition Efficiency

Technical report describing how to estimate the energy deposition efficiency of the kinetic energy of recoiling fragments from nuclear fission in a chemically reacting system. Since it is not always possible to directly measure the deposition the report describes how to estimate through the aid of fission fragment range data.

A New Chlorophyll from Green Bacteria (open access)

A New Chlorophyll from Green Bacteria

The green photosynthetic bacteria are characterized by the presence of either chlorobium chlorophyll (bacterioviridin)-65o or chlorobium chlorophyll-66o (numerical designation based on the position of the red-absorption peak in ether) z. Most strains of Chlorobium contain chlorophyll-66o which has its major red peak between 74 ° and 75 ° m/~ in FiFo. KATZ AND WASSINK z first reported an additional minor absorption peak at 81o mF for Chlorobium limicola in vivo and a corresponding minor peak at 780 m F in ethanol extracts. LARSEN (Figs. 6-11 in ref. 3) also observed this 8Io-mF absorption band in another Chlorobium strain and a corresponding peak at 77 ° m/~ in acetone extracts. In strain L of C. thiosulfatophilum the minor red peak appears at 800 mF, clearly resolved from the main peak of chlorophyll-65o at about 725 m/~ (see refs. I, 4). We have observed the minor red peak once again in Chloropseudomonas ethylicum, strain 2K (refs. 5, 6), as a shoulder at about 81o mF on the side of the 75o-mF peak of chlorophyll-66o (ref. 7). The evidence presented in this paper indicates that the absorption peak appearing between 800 and 81o m/, in vivo does not belong to chlorophyll-65 o (or …
