具有U_（qp）（U_3）U_（qp）（U_2）U_（qp）（SO_2）对称

A Two - Parameter Deformed Two - Dimensional Interacting Boson Model With U_(qp)(U_3)U(qp)(U_2)U(qp)(SO_2) Symmetry

构造了具有Ｕｑｐ（Ｕ３）Ｕｑｐ（Ｕ２）Ｕｑｐ（ＳＯ２）对称的双参数ｑｐ－形变二维相互作用玻色子模型（ＩＢＭ），并给出了其能谱和跃迁矩阵元．结果表明，能谱和跃迁矩阵元极其敏感地依赖于第二个形变参数．

A two-parameter deformed two-dimensional interacting boson model with Uqp(U3)Uqp(U2)Uqp(SO2)symmetry is constructed.It is found that the energy spectrum and transition matrix elements depend very sensitively on the second parameter of deformation.
