When a sharply cut-off Coulomb force with a cut-off radius $rho$ is introduced at the level of constituent particles, two-cluster direct potential of the Coulomb force becomes in general a local screened Coulomb potential. The asymptotic Hamiltonian yields two types of asymptotic waves; one is an approximate Coulomb wave with $rho$ in the middle-range region, and the other a free (no-Coulomb) wave in the longest-range region. The constant Wronskians of this Hamiltonian can be calculated in either region. We can evaluate the Coulomb-modified nuclear phase shifts for the screened Coulomb problem, using the matching condition proposed by Vincent and Phatak for the sharply cut-off Coulomb problem. We apply this method first to an exactly solvable model of the $alpha alpha$ scattering with the Ali-Bodmer potential and confirm that a complete solution is obtained with a finite $rho$. The stability of nuclear phase shifts with respect to the change of $rho$ in some appropriate range is demonstrated in the $alpha alpha$ resonating-group method (RGM) using the Minnesota three-range force. An application to the pd elastic scattering is also discussed.","PeriodicalId":49658,"journal":{"name":"Progress of Theoretical Physics","volume":"71 1","pages":"301-347"},"PeriodicalIF":0.0,"publicationDate":"2012-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1143/PTP.128.301","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64014684","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}

In the preceding paper, it is clarified that at high spins in 28Si+28Si (oblate-oblate system), the stable dinuclear configuration of the system is equator-equator touching one, and that the axially asymmetric shape of the stable configuration of 28Si+28Si gives rise to a wobbling motion ($K$-mixing). There, the normal modes around the equilibrium have been solved and various excited states have been obtained. Those states are expected to be the origin of a large number of resonances observed. Hence their physical quantities are analyzed theoretically. The results are compared with the recent experiment performed in Strasbourg and turn out to be in good agreement with the data. Disalignments between the orbital angular momentum and the spins of the constituent 28Si nuclei in the resonance state are clarified. Moreover the analyses of the angular correlations indicate characteristic features for each normal-mode excitation. Thus it is possible to identify the modes, and a systematic experimental study of angular correlation measurements is desired.","PeriodicalId":49658,"journal":{"name":"Progress of Theoretical Physics","volume":"127 1","pages":"877-905"},"PeriodicalIF":0.0,"publicationDate":"2012-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1143/PTP.127.877","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64011284","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}
