It is found that, in SD and SQ transitions, the RPA correlations associated with the tensor terms shin dramatically the strengths of ( Y l œÉ ) Œª = l ‚à? and ( Y l œÉ ) Œª = 1 modes upward and downward, respectively, and also shift the strengths of ( Y l œÉ ) Œª = l + 1 modes upward. The coupling between ( Y l = Œª ‚à?1 œÉ ) Œª and ( Y l = Œª + 1 œÉ ) Œª modes arising from the tensor correlation is noticeable. The RPA tensor correlations produce strengths of SD and SQ modes, which are distributed in a much wider energy range, and the ( Y l œÉ ) Œª = l ‚à?1 modes dominate the high energy part of the strength functions. These energy shifts and coupling effects of different modes can be understood qualitatively by expressing a finite range tensor force in a separable form.</style></abstract></record></records></xml>
