Mercury has seven stable isotopes and Hg isotope ratios can become a novel biogeochemical tool to track sources and. The Hg stable isotope results suggest that MDF and MIF are induced at different steps in the overall photochemical reduction reaction, and that MIF does not depend on the rate-determining step but instead depends on photophysical aspects of the reaction such as intersystem crossing and hyperfine coupling. The photochemical reduction of Hg(II) is an important pathway in the environmental Hg.

In the MEGAPIE target, mercury isotopes and their daughters (gold) were found in the cover gas, but only in the first fresh gas sample that was collected.7 The amount of experimentally detected mercury was much lower than the total amount of mercury in the system that was predicted by nuclear reaction codes. Consists of unresolved transition lines of the even isotopes of mercury, the most abundant of these being 200Hg and 202Hg. There are two other identifiable peaks - at −.351(8) cm−1 and.860(8) cm−1, respectively. The most probable identity of these peaks are the nuclear-spin split transition lines of the abundant, stable isotope 199Hg. [4].

Mercury-200 Information. Mercury is a heavy silvery liquid metallic element, belongs to the zinc group. It is used in thermometers, barometers and other scientific apparatus. This element is less reactive than zinc and cadmium, it does not displace hydrogen from acids. Mercury forms a number of complexes and organomercury compounds.
Mass-independent fractionation of mercury isotopes... - Nature.
Mercury. Mercury is the only metal which is liquid at room temperature. Two others melt close to room temperature (cesium at 28.5°C and gallium at 29.8°C). Because of its unreactivity, fluidity, high density, and high electrical conductivity, it finds many uses in scientific apparatus. Thermometers, barometers, and thermostats are common. For example, nuclear magnetic resonance (NMR) spectroscopy can be used only for isotopes with a nonzero nuclear spin. The most common isotopes used with NMR spectroscopy are 1 H, 2 D, 15 N, 13 C, and 31 P. Mössbauer spectroscopy also relies on the nuclear transitions of specific isotopes, such as 57 Fe. Radionuclides also have important uses. 3) Of Mercury's isotopes, 199Hg has a 1/2 integer spin and a positive magnetic moment. 111Ag and 113Ag both have an identical 1/2 integer nuclear spin. However, only 113Ag has a positive magnetic moment (compared to 111Ag's opposite or negative magnetic moment).

Recent reports have observed natural mass-dependent fractionation in mercury isotopes, and recent theoretical work has demonstrated that isotopic separation in mercury is due primarily to nuclear field shifts (nuclear volume effect), and the magnetic spin effect gives rise to mass-independent fractionation (MIF) of odd neutron number isotopes. The effectiveness of SOC in causing spin relaxation depends on magnetic quantum numbers of the isotopes and could also depend on the nuclear volume of the isotope. Smaller nuclear volume would likely increase the effectiveness of SOC in compounds where valence electrons are in the ‘s’ orbital (Khudyakov et al., 1993, Schauble, 2007).

Made available by U.S. Department of Energy Office of Scientific and Technical Information. Background: Shape coexistence in the Z ≈ 82 region has been established in mercury, lead, and polonium isotopes. For even-even mercury isotopes with 100 ≤ N ≤ 106 multiple fingerprints of this phenomenon are observed, which seems to be no longer present for N ≥ 110.According to a number of theoretical calculations, shape coexistence is predicted in the Hg 188 isotope. The toxicity of mercury's methylated species and its biomagnification in aquatic food chains and global dispersion by the atmosphere are the cause of worldwide health problems. Recent reports have observed natural mass‐dependent fractionation in mercury isotopes, and recent theoretical work has demonstrated that isotopic separation in mercury is due primarily to nuclear field shifts (nuclear.

Bergquist and Blum, 2007, suggested that the cause of MIF was the magnetic isotope effect (MIE), which is purely a kinetic phenomenon involving radical pair intermediates. Radical pairs with odd isotopes, which have non-zero nuclear spin and magnetic moments, can undergo spin conversion faster than radical pairs with non-magnetic even isotopes.

This indicates that a large increase in the effective nuclear volume of Hg occurs in going from N = 107 to N = 105. Recently, an optical pumping experiment on the neutron-deficient isotope 187Hg was reported [1]. It yielded the nuclear spin and moments as well as the isotopic shift of the spectral line X = 2537 A used for optical pumping.

The results show that spin-orbit coupling wipes out the potential of MIEs for Hg bound to Br or I, but that complexes involving lighter elements, HgX 2 and CH 3 HgX (X = Cl and SCH 3), have relatively small spin-orbit couplings upon photolysis. This unexpected finding shows that magnetic isotope fractionation due to hyperfine coupling is. Naturally occurring lithium (3 Li) is composed of two stable isotopes, lithium-6 and lithium-7, with the latter being far more abundant on Earth.Both of the natural isotopes have an unexpectedly low nuclear binding energy per nucleon (5 332.3312(3) MeV for lithium-6 and 5 606.4401(6) MeV for lithium-7) when compared with the adjacent lighter and heavier elements, helium (7 073.9156(4) MeV for.
