Mendelevium was discovered by bombarding einsteinium with alpha particles in 1955, the same method still used to produce it today.
22.
Using available microgram quantities of the isotope einsteinium-253, over a million mendelevium atoms may be produced each hour.
23.
This eliminates the need for immediate chemical separation, which is both costly and prevents reusing of the expensive einsteinium target.
24.
The reactor synthesis is followed by a complex process of separating einsteinium-253 from other actinides and products of their decay.
25.
Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952, and named after Albert Einstein.
26.
In particular, einsteinium was used to synthesize, for the first time, 17 atoms of the new element mendelevium in 1955.
27.
Thus, most einsteinium samples are contaminated, and their intrinsic properties are often deduced by extrapolating back experimental data accumulated over time.
28.
Milligrams of einsteinium that would normally take a year of irradiation in a high-power reactor, were produced within a microsecond.
29.
In order to reduce the self-radiation damage, most measurements of solid einsteinium and its compounds are performed right after thermal annealing.
30.
Einsteinium ( III ) fluoride ( EsF 3 ) can be precipitated from einsteinium ( III ) chloride solutions upon reaction with fluoride ions.
