Californium gleaming.
A late actinide with twenty known isotopes, californium is a manmade transuranic element that does not occur naturally. It was first identified by Glenn Seaborg and co-workers in February 1950 in an experiment that used a 60-inch cyclotron to bombard curium-242 targets with helium ions. Although named primarily for the State of California, it also recognizes the University of California at Berk...
متن کاملCHAPTER ELEVEN CALIFORNIUM Richard
The discovery of californium came in the era of the syntheses and identifications of other transplutonium elements, following the end of World War II. The discovery of the element californium, like many of the other actinide elements, hinged on the development of new experimental techniques in conjunction with predictions based on nuclear systematics. Californium was named after the University ...
متن کاملAbsorption and emission spectrum
It is well known that main group metal ions with an s* electron configuration form a large variety of polynuclear coordination compounds [l]. Recently it has been suggested that in these compounds a weak metal-metal bonding may exist which is achieved by sp orbital mixing [2]. In particular, calculations on Tl+ clusters were used to support this idea. Unfortunately, the metal-metal interaction ...
متن کاملPulsar Emission Spectrum
Here we calculate pulsar emission, apparently from first principles, i.e., without any arbitrary assumptions. Our method applies to weak pulsars. A pulsar is called weak if pair production near the light cylinder is negligible compared to Goldreich-Julian density [1] per rotation. The weak pulsar approximation must be accurate for some, and perhaps meaningful for most, Fermi [2] pulsars. We tre...
متن کاملThe M Emission Spectrum of 68Erbium.
The M emission spectrum of 68Er was reinvestigated using wavelength dispersive spectrometry, with a TAP diffracting crystal. By recording the spectra using the second-order reflection, an improved energy resolution was achieved, which is necessary to resolve the M5O3 line from the neighboring alpha M5N7 transition. In addition to the five lines/bands tabulated in the classical paper of Bearden,...
