Abstract
We extend the microscopic particle-rotor model for hypernuclear low-lying states by including the derivative and tensor coupling terms in the point-coupling nucleon -particle interaction. Taking as an example, we show that a good overall description for excitation spectra is achieved with four sets of effective interactions. We find that the hyperon binding energy decreases monotonically with increasing strengths of the high-order interaction terms. In particular, the tensor coupling term decreases the energy splitting between the first and states and increases the energy splitting between the first and states in .
