Book Description
Isotopes are varieties of a single chemical element having different atomic weights. Thus, for instance, tin (atomic weight 118.70) has 10 isotopes with atomic weights of 112, 114, 115, 116, 117, 118, 119 120 122, 124. Because the charge of their atomic nuclei is the same, all of them occupy one and the same place in the periodic table of Mendeleyev.

Book Description
A process for separating isotopes by selective excitation of isotopic species of a volatile compound by tuned laser light. A highly cooled gas of the volatile compound is produced in which the isotopic shift is sharpened and defined. Before substantial condensation occurs, the cooled gas is irradiated with laser light precisely tuned to a desired wavelength to selectively excite a particular isotopic species in the cooled gas. The laser light may impart sufficient energy to the excited species to cause it to undergo photochemical reaction or even to photoionize. Alternatively, a two-photon irradiation may be applied to the cooled gas to induce photochemical reaction or photoionization. The process is particularly applicable to the separation of isotopes of uranium and plutonium.

Book Description
To find a process for successful photochemical separation of isotopes several conditions have to be fulfilled. First, the different isotopes have to show some differences in the spectrum. Secondly, and equally important, this difference must be capable of being exploited in a photochemical process. Parts A and B outline the physical and chemical conditions, and the extent to which one might expect to find them fulfilled. Part C deals with the applicability of the process.

Book Description
The effluent from mercury collected during the photochemical separation of the .sup. 196 Hg isotope is often contaminated with particulate mercurous chloride, Hg.sub. 2 Cl.sub. 2. The use of mechanical filtering via thin glass tubes, ultrasonic rinsing with acetone (dimethyl ketone) and a specially designed cold trap have been found effective in removing the particulate (i.e., solid) Hg.sub. 2 Cl.sub. 2 contaminant. The present invention is particularly directed to such filtering.
