Abstract
The ground state proton momentum distributions and elastic charge form factors for <sup>88</sup>Sr and <sup>89</sup>Y nuclei have been derived and studied using the Coherent Density Fluctuation Model and formulated by means of the fluctuation function (weight function) |<i>f(x)</i>|<sup>2</sup> The fluctuation function has been connected to the charge density distribution of the nuclei and determined from the theory and experiment. The feature of the long-tail behavior at high momentum region of the PMD has been calculated by both the theoretical and experimental fluctuation functions. The calculated form factors F (q) of all nuclei under study are in good agreement with those of experimental data throughout all values of momentum transfer q.
Highlights
The most accurate determination of the charge distributions in nuclei can be obtained from electron-nucleus scattering
The derived form of the CDD is employed in determining the theoretical weight function f (x) 2 which is used in the coherent density fluctuation model (CDFM) to study the proton momentum distribution (PMD) and elastic electron scattering charge form factors for 88Sr and 89Y nuclei
The proton momentum distributions n(k) and elastic form factors, F(q), for 88Sr and 89Y nuclei are studied by means of the CFM
Summary
The most accurate determination of the charge distributions in nuclei can be obtained from electron-nucleus scattering. AL-Rahmani [15] has measured the nucleon momentum distributions and elastic electron scattering form factor of the ground state for some odd 2s-1d shell nuclei like (19F, 25Mg, 27Al and 29Si) by using the coherent density fluctuation model and expressed in terms of the fluctuation function(weight function) |f(x)|2. Through her works she found that the inclusion of the quadrapole form factors FC2 (q) in all nuclei under study which was described by the undeformed 2S-1d shell nuclei, was essential for obtained a notable accordance between the experimental and theoretical form factors. The derived form of the CDD is employed in determining the theoretical weight function f (x) 2 which is used in the CDFM to study the proton momentum distribution (PMD) and elastic electron scattering charge form factors for 88Sr and 89Y nuclei
