Einsteinium ( III ) fluoride ( EsF 3 ) can be precipitated from einsteinium ( III ) chloride solutions upon reaction with fluoride ions.
32.
Chemical element " symbols " ( such as Cf for californium and Es for einsteinium ), are always capitalized ( see below ).
33.
The einsteinium separated by this method has the advantage to be free of organic complexing agent, as compared to the separation using a resin column.
34.
Irradiation of 241 Am by 12 C or 22 Ne ions yields the isotopes 247 Es ( einsteinium ) or 260 Db ( dubnium ), respectively.
35.
Other experimental techniques to circumvent the contamination problem include selective optical excitation of einsteinium ions by a tunable laser, such as in studying its luminescence properties.
36.
Irradiation of 241 Am by 12 C or 22 Ne ions yields the isotopes 253 Es ( einsteinium ) or 263 Db ( dubnium ), respectively.
37.
The high radioactivity of einsteinium-253 produces a visible glow and rapidly damages its crystalline metal lattice, with released heat of about 1000 watts per gram.
38.
Einsteinium-247 ( half-life 4.55 minutes ) was produced by irradiating americium-241 with carbon or uranium-238 with nitrogen ions.
39.
Einsteinium and fermium were discovered by a team of scientists led by Albert Ghiorso in 1952 while studying the radioactive debris from the detonation of the first hydrogen bomb.
40.
Of the actinides, environment; analysis of debris from a 1952 hydrogen bomb explosion showed the presence of americium, curium, berkelium, californium, einsteinium and fermium.
