The charge densities in these isotopes have been also researched by the one and two particle components of cluster series using single-particle wavefunctions of the harmonic oscillator potential. The short range effects have been inserted into the two particle components of cluster series employing the Jastrow form correlation. The total form factors of isotopes under consideration arise from the model space and core-polarization participations. The one-body density matrix elements (which are needed for computing the model space transition charge density) of valence nucleons for the transition [Formula: see text] have been computed by accomplishment of shell model calculations using the OXBASH code with various interactions. The shape of Tassie model has been adopted for computing the core-polarization transition charge density. The present computations are reliant on [Formula: see text] (oscillator parameter) and [Formula: see text] (correlation parameter), where these parameters have been created independently for each individual nucleus by fitting the computed elastic form factors to those of experimental ones. This study provides a proof for strong ascendancy of short range effects on the present calculations, where inclusion of short range correlations on computations seems to be required for performing a notable modification in the computed outcomes which sequentially causes to elucidate the experimental data astoundingly in the momentum transfer under consideration.","PeriodicalId":50306,"journal":{"name":"International Journal of Modern Physics E","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47672190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The calculations agree well with the experimental data in the whole energy region except from 20,MeV to 50,MeV at backward angles, where there is an upward trend for the experimental data of angular distributions. Besides, the inelastic scattering contributions of the first excited states are deduced by the present global optical potential. The results are also in good agreement with the experimental data. In order to improve the description of elastic scattering, the inelastic scattering contributions of the first excited states are considered in the calculations between 20 and 50,MeV.

In DCM, the fusion excitation functions are calculated using sticking [Formula: see text] and nonsticking [Formula: see text] limits of the moment of inertia. For the chosen reactions, fusion cross-sections are equivalent to evaporation residue (ER) cross-sections [Formula: see text] as fission cross-sections are negligible. A lower magnitude of maximum angular momentum [Formula: see text] is obtained via the [Formula: see text] approach in comparison to the [Formula: see text] approach and the angular momentum obtained via the [Formula: see text] approach is closer to the experimental observations. The structure and magnitude of fragmentation potential and preformation probability [Formula: see text] depend on the choice of moment of inertia and the magnitude of angular momentum involved. Besides this, PACE4 is employed to address the fusion cross-section of chosen reactions.
