The α-nucleus potential was derived by employing the double-folding model with a realistic NN interaction whose exchange part has a finite-range. We considered several isotopes for each Z-value. The behavior of log Tα against the neutron number variation for different isotopes of each element is investigated. We found a clear similarity in the behavior of log Tα for the isotopes of a number of successive elements. The proton pair in the emitted α particle, for these elements, comes from the same proton energy level. Also, the behavior of log Tα with the parent neutron number, for different isotopes of an element, was found to be governed by the existence of neutron magic number or neutron-level closure. The possibility to correlate the behavior of log Tα for several isotopes of a specific element with the proton and neutron energy levels of this element is investigated. Moreover, the behavior of log Tα when adding successive proton pairs to fill the energy level at different neutron numbers is studied. This work can be considered as a significant step forward to correlate the behavior of log Tα with the energy levels.","PeriodicalId":14032,"journal":{"name":"International Journal of Modern Physics E-nuclear Physics","volume":"617 1","pages":"2050065"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77618007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These formulae are used to deduce the band-head spins of the nine superdeformed bands in A ∼ 190 mass region and two superdeformed bands of A ∼ 150 mass region. The band-head spins of these superdeformed bands have been established experimentally and hence they prove to be excellent candidates to examine the adequacy of rotational energy formulae in superdeformed bands. The least-squares fitting of γ-transition energies is performed to calculate the model parameters such as the band-head moment of inertia, the effective pairing gap parameter and the softness parameter, and a careful analysis of these parameters is made. For the first time, we have performed a systematic study of the rotational energy formulae to establish which formula gives the best estimate of spin in A ∼ 190, 150 mass regions.","PeriodicalId":14032,"journal":{"name":"International Journal of Modern Physics E-nuclear Physics","volume":"1 1","pages":"2050081"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78779810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
