主　　题：hypernuclear microscopic cluster model resonance 

摘      要：The application scope of the analytic continuation in the coupling constant(ACCC)can be extended to the exchange parameters of the effective nucleon-nucleon interaction in the microscopic cluster *** on such an exchange parameter dependent ACCC(abbreviated as EPD-ACCC),we examine the_(∧)^(9)Be system in the framework of theα+Q+∧microscopic cluster *** particle emission from excited states ofα+α+∧are investigated,and the corresponding resonant energies are obtained via ***,the complex scaling method(CSM)is applied for comparison.A good agreement between these two theoretical approaches is *** study demonstrates EPD-ACCC to be a reliable method for estimating multi-cluster resonances in light hypernuclei.
