Nuclear isomers
WebHere, we examine the rates for electromagnetic excitation of the isotopes of several isomers of interest both in astrophysics and applied physics (e.g., 235 U, 193 Ir, and 87,88 Y). We consider six possible electromagnetic processes, namely, photoabsorption, inverse internal conversion, inelastic electron scattering, coulomb excitation, and ( , ') and ( e , e ' … WebA two isotopes and no isomers B three isotopes and two nuclear isomers C three isotopes and two optical isomers D two isotopes and two geometrical isomers.

A nuclear isomer is a metastable state of an atomic nucleus, in which one or more nucleons (protons or neutrons) occupy higher energy levels than in the ground state of the same nucleus. "Metastable" describes nuclei whose excited states have half-lives 100 to 1000 times longer than the half-lives of the … Meer weergeven The nucleus of a nuclear isomer occupies a higher energy state than the non-excited nucleus existing in the ground state. In an excited state, one or more of the protons or neutrons in a nucleus occupy a nuclear orbital of … Meer weergeven Most nuclear excited states are very unstable and "immediately" radiate away the extra energy after existing on the order of 10 seconds. As a result, the characterization "nuclear isomer" is usually applied only to configurations with half-lives of 10 … Meer weergeven The most common mechanism for suppression of gamma decay of excited nuclei, and thus the existence of a metastable isomer, is lack of a decay route for the … Meer weergeven An isomeric transition or internal transition (IT) is the decay of a nuclear isomer to a lower-energy nuclear state. The actual process has two types (modes): • γ (gamma ray) emission (emission of a high-energy photon), • internal conversion (the energy … Meer weergeven Metastable isomers can be produced through nuclear fusion or other nuclear reactions. A nucleus produced this way generally starts its existence in an excited state that relaxes through the emission of one or more gamma rays or conversion electrons. … Meer weergeven Hafnium isomers (mainly Hf) have been considered as weapons that could be used to circumvent the Nuclear Non-Proliferation Treaty, since it is claimed that they can be induced to emit very strong gamma radiation. This claim is generally discounted. Meer weergeven • Induced gamma emission • Isomeric shift Meer weergeven WebNuclear isomers are also known to have many useful applications and some of them promise to have still newer applications. Our “Atlas of Nuclear Isomers” [1] lists more than 2460 isomers with a lower limit of half-life at 10 ns. It is quite interesting to look for the various regions in the nuclear chart where isomers exist.
