Microscopic method for E0 transition matrix elements

et al. 2017

We present a microscopic model for electric monopole (E0) transition matrix elements by combining a configuration interaction model for orbital occupations with an energy-density functional model for the single-particle potential and radial wavefunctions. The configuration interaction model is used to constrain the orbital occupations for the diagonal and off-diagonal matrix elements. These are used in an energy-density functional calculation to obtain a self-consistent transition density. This density contains the valence contribution, as well as the polarization of the protons by the valence protons and neutrons. We show connections between E0 matrix elements and isomer and isotope shifts of the charge radius. The spin-orbit correction to the charge density is important in some cases. This model accounts for a large part of the data over a wide region of the nuclear chart. It also accounts for the shape of the observed electron scattering form factors. The results depend on the Skyrme parameters used for energy-density functional and might be used to provide new constraints for them.

“…A number of explanations for the occurence of low lying 0 + states in transitional nuclei in general [20] and in even Zr and Mo isotopes in particular [29,24,30,31] have been proposed. Among these are pairing vibrations [29], band heads of fi-vibrations [31], states orthogonal to the ground state [30] and band heads of rotational and vibrational bands caused by a coexistence of spherical and deformed nuclear shapes [7] (see Fig. 1).…”

The?-decay of100Y: Discovery of a very low lying 0+ state in100Zr

et al. 1977

View full text Add to dashboard Cite

The /?-decay of lOOy has been investigated at the gas filled recoil separator JOSEF by means of 7-ray and conversion electron spectroscopy. Two B-decay modes, of half lives 0.94 + 0.03 s and 0.55 _+ 0.15 s, have been observed. Using XV-, Xce-, V7-and 7ce-coincidences the level scheme of ~~176 has been constructed. An excited 0~-state at 331.3 keV has been discovered in this nucleus. The/~-decay from the 0.55 s decay mode in 10oy shows a strong preference for the ground state compared to the 0~-state in ~~176 The structure of l~176 and the nature of the 0~ level is discussed in the light of the present results.

⁹⁰Y ‐PET imaging: Exploring limitations and accuracy under conditions of low counts and high random fraction

et al. 2015

View full text Add to dashboard Cite

Due to the low counts and high random fraction, accurate image quantification of (90)Y during selective internal radionuclide therapy is affected by random coincidence estimation, scatter correction, and any positivity constraint of the algorithm. Nevertheless, phantom and patient studies showed that the impact of number of true and random coincidences on quantitative results was found to be limited as long as ordinary Poisson ordered subsets expectation maximization reconstruction algorithms with random smoothing are used. Adding PSF correction and TOF information to the reconstruction greatly improves the image quality in terms of bias, variability, noise reduction, and detectability. On the patient studies, the total activity in the field of view is in general accurately measured by Biograph mCT and slightly overestimated by the Biograph TruePoint.
