New charge radius relations for atomic nuclei

et al. 2014

We show that the charge radii of neighboring atomic nuclei, independent of atomic number and charge, follow remarkably very simple relations, despite the fact that atomic nuclei are complex finite many-body systems governed by the laws of quantum mechanics. These relations can be understood within the picture of independent-particle motion and by assuming that neighboring nuclei have similar patterns in the charge density distribution. A root-mean-square (rms) deviation of 0.0078 fm is obtained between the predictions in these relations and the experimental values, i.e., a precision comparable modern experimental techniques. Such high accuracy relations are very useful to check the consistence of the nuclear charge radius surface and moreover to predict unknown nuclear charge radii, while large deviations from experimental data are seen to reveal the appearance of nuclear shape transition or coexsitence.PACS numbers: 21.10. Ft, 21.90.+f, 27.70.+q, 29.87.+g Like many systems governed by the laws of quantum mechanics, the nucleus is an object full of mysteries whose properties are much more difficult to characterize than those of macroscopic objects. Rather than build an exact replica of the nuclear system (almost an impossible job), nuclear physicists in reality have selected a different approach, using a relatively small number of measurable properties of quantum systems to specify the overall characteristic of the entire nucleus. Investigations of these properties and moreover using them as bridges to reveal the atomic nucleus, form the basis of present nuclear physics investigations. Nuclear extension in space, often characterized by charge radius, is one of such static properties.Nowadays, nuclear size data [1] constitute one of the most precise and extensive arrays of experimental information available for the interpretation of nuclear phenomena. The pioneering works by using various methods such as electron scattering and muonic atomic spectroscopy [2], indicated that a nuclide near the β-stability line behaves like a solid sphere with constant density. In recent decades, the enormous progress in size determination of exotic nuclides has been entwined with the realization of radioactive ion beams [3] and fast developments especially in ultra-high-sensitivity laser spectroscopy techniques [4,5]. The new measurements contributed to revealing, for example, the neutron skin effect [6,7] and the nuclear shape variances [8][9][10] when moving far away from the stability line.

Charge-changing cross sections at high energies are expected to provide useful information on nuclear charge radii. No reliable theory to calculate the cross section has yet been available. We develop a formula using Glauber and eikonal approximations and test its validity with recent new data on carbon isotopes measured at around 900A MeV. We first confirm that our theory reproduces the cross sections of 12,13,14 C + 12 C consistently with the known charge radii. Next we show that the cross sections of 12−19 C on a proton target are all well reproduced provided the role of neutrons is accounted for. We also discuss the energy dependence of the charge-changing cross sections. DOI: 10.1103/PhysRevC.94.011602 A study of unstable nuclei is one of the fields that have been promoted most intensively. Charge distribution or charge radius, among others, is one of the fundamental quantities to characterize the ground-state properties of nuclei. Electron scattering measurement is ideal for probing the distribution but so far not applicable to short-lived unstable nuclei. We note, however, that the electron-ion scattering experiment will be available in the near future, as planned in Refs. [1,2]. Isotope shift measurement allows us to precisely deduce the charge (proton) radius for some limited unstable nuclei. The measurement of the charge-changing cross section (CCCS) newly appears as a potential means to extract the proton radius since it has the great advantage that the cross section can be measured for almost all nuclei by the same setup as the total reaction or interaction cross section that plays a decisive role in determining the nuclear matter radius [3]. In fact the CCCS has recently been measured to get information on the proton radii of light unstable nuclei [4][5][6][7][8].A theoretical tool for extracting the matter radius from the high-energy total reaction cross sections is well established with the help of Glauber theory [9]. See Refs. [10,11] for a useful application to determining both proton and neutron radii. The reaction mechanism for the charge-changing reaction (CCR) is, however, not well understood and energydependent adjustments are introduced to analyze the CCCS data [4][5][6]12], which makes it difficult to obtain proton radii from the measurement. The purpose of this paper is to show * Present address: Department of Physics, Niigata University, Niigata 950-2181, Japan.that recent new CCCS data of carbon isotopes on both 12 C [13] and proton targets are all satisfactorily reproduced in the framework of the Glauber and eikonal models. The role of neutrons becomes evident for the proton target. This is an important step toward constructing a method of analyzing CCCSs with the use of no adjustable parameters.The total reaction cross section can be calculated bywhere b is a two-dimensional (2D) impact parameter vector perpendicular to the beam (z) direction, |0 = |0 P 0 T is a product of the projectile and target ground-state wave functions, and, e.g., χ p is a sum of the phase-shift functions χ...

Short-range correlations and the3s1/2wave function inPb206

Charge density difference between 206 Pb and 205 Tl, measured by elastic electron scattering, offers a unique opportunity to look for effects of short range correlations on a shell model wave function of a single proton. The measured difference is very similar to the charge density due to a proton in a 3s 1/2 orbit. If there is a potential whose 3s 1/2 wave function yields the measured difference between the charge distributions, no effect of short range correlations is evident. To check this point, we look for a potential whose 3s 1/2 wave function yields the measured data. We developed a novel method to obtain the potential directly from the density and its first and second derivatives. Fits to parametrized potentials were also carried out. The 3s 1/2 wave functions of the potentials determined here, reproduce fairly well the experimental data within the quoted errors. To detect possible effects of two-body correlations on the 3s 1/2 shell model wave function, more accurate measurements are required.
