Occurrence of the (4n + 1) Series in Nature

Autor: G.W. Mason, J. F. Mech, D.F. Peppard, P. R. Gray

Publikováno v: Journal of the American Chemical Society. 74:6081-6084

"A small quantity of a Np-237, the long-lived ancestor of the 4n + 1 series, has been isolated from a natural source. The Th-229 content of the Th-230 obtained from Belgian Congo pitchblende concentrate and of Th-232 obtained from Brazilian monazite

The November 1, 1952 thermonuclear explosion ("Mike") produced all of the uranium isotopes ${\mathrm{U}}^{239}$, ${\mathrm{U}}^{240}$,...${\mathrm{U}}^{255}$ through multiple neutron capture by ${\mathrm{U}}^{238}$. The long-lived products of success

Berkelium and Californium Isotopes Produced in Neutron Irradiation of Plutonium

Autor: Arnold M. Friedman, P. R. Fields, Herbert Diamond, J. F. Mech, C. M. Stevens, L. B. Magnusson, Martin H. Studier, J.R. Huizenga

Publikováno v: Physical Review. 96:1576-1582

Californium isotopes of mass numbers 249, 250, 251, and 252 have been identified by mass spectrometric analyses of californium samples produced from neutron-irradiated plutonium. The half-lives of ${\mathrm{Bk}}^{249}$, ${\mathrm{Cf}}^{249}$, ${\math

Transplutonium Elements in Thermonuclear Test Debris

Autor: P. R. Fields, Mark G. Inghram, G. L. Pyle, S. Fried, G. H. Higgins, Stanley G. Thompson, W. M. Manning, Glenn T. Seaborg, C. M. Stevens, J. F. Mech, Herbert Diamond, Martin H. Studier, Albert Ghiorso

Publikováno v: Physical Review. 102:180-182

The isotopes of curium, berkelium and californium found in the thermonuclear debris of the November 1952 thermonuclear test are discussed. The instantaneous buildup of the heavy elements in the thermonuclear device is compared with the buildup during
