摘要
研究多原子晶体中体极化子内部激发态的性质 ,采用么正变换和Huybrechts的方法计算了多原子晶体中弱耦合体极化子的激发能量 .结果表明 ,体极化子的基态能量和激发能量表示为耦合常数α的幂级数 .
In this paper,the properties of internal excited state of bulk polaron in a polyatomic crystals are studied.The excitation energy of weak-coupling bulk polaron in a polyatomic crystals were calculated by unitary transformation and Huybrechts's methods.The results show that the ground state energy and the excitation energy of bulk polaron may be written as a series of α the coupling constant.
