Abstract：
In order to investigate the S-D truncation in the interacting boson model,s′-boson is considered to enlarge the collective subspace.The structures of the s,d and s′-bosons are determined in terms of one of the microscopic IBM approaches.The calculation and discussion of the s′-boson and the system including one s′-boson show that ,although the s′-boson has little contribution to the excited states below 2MeV which are already well described by the sd IBM,it is expected that the introducing of the s′-boson may extend the applicability of the model to a number of states above 2MeV.
