Parameters of widely used nuclear rms charge radius formulas have been refitted based on the latest experimental data for about 900 nuclei. It has been seen that the new parameters in the formulas give better results than the previous ones. Besides, an N1/3-dependent formula has been proposed...

A semi-empirical formula for the nuclear radius 来自 Semantic Scholar 喜欢 0 阅读量: 24 作者: LRB Elton 摘要: It is shown that the experimental results on negaton and proton scattering by nuclei are in agreement with the assumptions that the central density of nuclear matter is constant for ...
The extended kernel ridge regression (EKRR) method with odd–even effects was adopted to improve the description of the nuclear charge radius using five commonly used nuclear models. These are: (i) the isospin-dependentA1/3formula, (ii) relativistic continuum Hartree–Bogoliubov (RCHB) theory, ...
where the constantais close to but not the same asr0and depends on the physical phenomena involved in the measurement. In the case of the nuclear charge radius, measured from the scattering of electrons by nuclei or from the position of the energy levels of μ,-mesonic atoms,a= 1.12 fm ...
A nuclear mass formula is constructed which is composed of two parts, one describing the general trend of the masses as a function of Z and N and the other representing deviations of individual masses from this general trend. These deviations are referred to as shell energies in a broad sense...
An improved Z~(1/3) law of nuclear charge radius is presented. The comparison between the calculated and experimental nuclear charge radii now available shows that this new formula is better than the other conventional formulae.doi:10.1088/0253-6102/51/1/23LEI Yi-AnZHANG Zhen-Hua理论物理通讯...
This creates a smaller atomic radius, higher ionization energy, and higher net positive charge on the atom. How do you find the effective nuclear charge of an atom? To find the effective nuclear charge of an atom, use the formula, Zeff = Z - S, where Z is the atomic number and S ...
Step 2: Calculate the radius of the nucleusThe radius R of the nucleus can be calculated using the formula:R=R0A1/3where R0 is a constant approximately equal to 1.2×10−15 m. Substituting the values:R=1.2×10−15×(54)1/3 Calculating (54)1/3:(54)1/3≈3.78Now substituting this...
Meanwhile, the Electron-Ion Collider (EiC) plans to construct a fully silicon-based tracking detector, projected to be 242 cm long and 43.2 cm in radius. As shown in Fig.26, six layers will provide tracker coverage for low values of pseudorapidity. They are laid out in three double layers...
