摘　　要：固体氦是具有量子特性的量子固体。在Morse势模型下分析稀有气体双原子分子的束缚态,定义Morse势的有效宽度。在Lennard-Jones势模型下,采用经典方法计算结合能,结合量子力学不确定性原理估算零点能修正的方法,分析一维4He原子链的基态能量和晶格常数,对量子固体氦的基态进行讨论。Solid helium is a quantum solid with unique quantum properties.Bound state of rare gas diatomic molecules under the Morse potential model is analyzed,and the effective width of the Morse potential is defined.Under the Lennard-Jones potential model,the ground-state energy and lattice constants of the one-dimensional 4He atomic chain are analyzed,where the binding energy is calculated by classical method and the zero-point energy correction is estimated by quantum mechanical uncertainty principle,and the ground state of quantum solid helium is discussed.
