After confirming the neutron capture cross section of 186 W (σ 0 = 37.8 ± 1.8 b for thermal and I 0 = 476 ± 25 b for resonance integrals with σ 0 /I 0 = 12.6 ± 0.4) in two short irradiations, longer irradiations (1–10 d) were performed to obtain a value of 6.5 ± 0.8 b for the σ 0 of 187 W, which is lower than the adopted value by a

A table or chart of nuclides is a two-dimensional graph of isotopes of the elements, in which one axis represents the number of neutrons and the other represents the number of protons in the atomic nucleus. Each point plotted on the graph thus represents a nuclide of a known or hypothetical chemical element. This system of ordering nuclides can offer a greater insight into the characteristics of isotopes than …

Gonadotropin‐releasing hormone (GnRH) receptor antagonists are an important class of compounds designed to block the pituitary gland from synthesizing follicle‐stimulating hormone and luteinizing hormone for the treatment of sex hormone dependent disorders. Tungsten 184 Trioxide (Tungsten-184) is a stable (non-radioactive) isotope of Tungsten. It is both naturally occurring and produced by fission.

Atomic mass of Osmium is 190.23 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.
