Is the 7/2(1)- isomer state of 43S spherical?

چکیده
We report on the spectroscopic quadrupole moment measurement of the 7/2(1)(-) isomeric state in (16)(43)S(27) [E*=320.5(5) keV, T(1/2)=415(3) ns], using the time dependent perturbed angular distribution technique at the RIKEN RIBF facility. Our value, |Q(s)|=23(3) efm(2), is larger than that expected for a single-particle state. Shell model calculations using the modern SDPF-U interaction for this mass region reproduce remarkably well the measured |Q(s)|, and show that non-negligible correlations drive the isomeric state away from a purely spherical shape.

6 ABSTRACT: The S2 redox intermediate of the oxygen-evolving 7 complex in photosystem II is present as two spin isomers. The S = 8 1/2 isomer gives rise to a multiline electron paramagnetic resonance 9 (EPR) signal at g = 2.0, whereas the S = 5/2 isomer exhibits a broad 10 EPR signal at g = 4.1. The electronic structures of these isomers are 11 known, but their role in the catalytic cycle of wa...

The combined effect of hydrostatic pressure and temperature on correlation energy in a triplet state of two electron spherical quantum dot with square well potential is computed. The result is presented taking GaAs dot as an example. Our result shows the correlation energies are i)negative in the triplet state contrast to the singlet state ii) it increases with increase in pressure iii)further...

New experimental results on 43S and 44S reveal that these nuclei are located in a transitional region of prolate-spherical shape coexistence between the spherical 48Ca and the oblate 42Si. The origin of the deformation is discussed in terms of the evolution of the single particle energy levels leading to the compression of the orbitals in the sd and p f shells for protons and neutrons, respecti...

In this work, an equation of state has been utilized for thermodynamic modeling of aqueous electrolyte solutions. The proposed equation of state is a combination of simplified statistical associating fluid theory (SAFT) equation of state (similar to simplified PC-SAFT) to describe the effect of short-range interactions and mean spherical approximation (MSA) term to describe the effect of long-r...
