Brief descriptions are also found in two volumes of this handbook [15, 16], which should be consulted for further explanations of special notations used for instance in decay schemes.

H.F. Jelinek,N. Elston,B. ZietschAstatine (At), element 85, has no stable isotopes. Its longest-lived isotope, .At, has a half-life of only 8.3 h and a specific activity of 1.8 Ci/µg. Consequently, studies of At chemistry have necessarily been limited to trace levels on the order of 10. to 10. M. General reviews of At chemistry are given by [1 to 16].
