The shell model calculations relied on assumptions about the disregarded core-polarization effects and the utilization of effective charges. We performed extensive theoretical calculations to determine the probability of reduced electric quadrupole transition, B(E2;0g.s+ → 2+), the intrinsic quadrupole moments (Q0), the deformation parameters (β2,δ), and the inclusion of effective interactions such as fpd6, fpv, fpbm, and kb3. Using the NuShellX@MSU algorithm, the one-body density matrix elements (OBDM) were computed for these isotopes. Various effective charges were utilized in these computations, including NU-E effective charges obtained from the Nushellx@MSU software, ST-E standard effective charges, and BM-E effective charges calculated using Bohr and Mottelson’s method. Comparative analysis was conducted between the theoretical values of transition rate B(E2), intrinsic quadrupole moments, deformation parameters and the available experimental data. The gained theoretical conclusions were subsequently contrasted with prior experimental data, which had similarly demonstrated the collapse of the magical property of the Cr isotope. The intrinsic quadrupole moment was optimal when employing the kb3 interaction, but the deformation parameter appeared optimal when using two interactions, fpbm and kb3. Furthermore, it has been demonstrated that the magical characteristic of the 52Cr (N = 28) isotope undergoes collapse.</div>","PeriodicalId":584,"journal":{"name":"Indian Journal of Physics","volume":"99 6","pages":"2191 - 2206"},"PeriodicalIF":1.6,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938355","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}

It is assumed that after a certain moment the probability of interaction of neutrinos with other particles and between itself is small, neutrinos become free. In this case, the component of the neutrino momentum along the axis at which compression occur increases due to the \"blue\" shift. The distribution of neutrino momentum becomes sharply anisotropic, elongated in the direction of compression, and the energy of each neutrino increases. In this stage, the neutrinos generated by the mixing of mass and flavor oscillate. If right hand neutrinos and left hand antineutrinos exist, their interaction with matter should be much weaker than the weak interaction of the flavor left hand neutrinos and right hand antineutrinos should be “sterile” neutrinos. In this paper we consider the dynamics of neutrino oscillations associated with a homogeneous but anisotropic Universe within the framework of a stochastic model. Expressions are obtained for the mixing angles, probabilities, and lengths of three neutrino oscillations. The study of oscillation probabilities makes it possible to determine the hierarchy of neutrino masses and the violation of CP symmetry in the neutrino sector. The results obtained in this work clearly show that a phase shift of neutrino oscillations can appear depending on the anisotropy of space.</div>","PeriodicalId":584,"journal":{"name":"Indian Journal of Physics","volume":"99 6","pages":"2339 - 2343"},"PeriodicalIF":1.6,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938629","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}
