A direct determination of the abundance of the isotopes of lithium which occurs as a trace element in the Holbrook meteorite is reported. The measurement was performed with an ion-microprobe mass-spectrometer which permits analysis of very small portions of the meteorite surface without chemical ...
of isotopes of lead showed, however, a remarkable discrepancy between the shift predicted by the theory and that actually observed. Similarly Merton's experiments on the line 6708 of lithium showed that the line consisted of two components 0.151 脜. apart, while the theoretical shift was 0.087 ...
(n = 20)32,33,34. The hard-rock deposits, mostly Li-rich granitic pegmatite, are interpreted as the product of fractional crystallisation from a parental granitic melt. Lithium is a major element in various minerals, such as amblygonite, bikitaite, eucryptite, lithiophilite, li...

Isotopes are variants of chemical elements: while all isotopes of a given element contain the same number of protons, they vary in the number of neutrons they contain. Variation in neutron number produces chemically identical atoms with different masses,
Every nucleus of a given element must contain the same number (Z) of protons, but these nuclei can contain different numbers of neutrons. Most hydrogen atoms have nuclei that consist of a single proton, but a small fraction (about 0.015 percent) of the hydrogen atoms that occur in Nature ...
The element "lithium" has strong absorption lines near 6707.84 A and 3232.61 A and possesses specific isotope shifts at the respective absorption lines. With the aid of a laser capable of controlling the oscillation spectral width accurately to 0.01 A, the isotopes of this element are separated ...
