摘要
设计内表面微量氧化的封闭Pb~(207)(I=1/2)金属圆筒模型与球壳模型,在使用超导量子干涉仪测量内表面氧化物β-Pb~(207)O声核信号的前提下,分别进行公式推导与验证,为后续实验测量半导体材料中的偶极矩耦合信号进行理论计算。在相应的条件下,得到超导量子干涉仪磁通变化与可测量的氧化物质量范围以及所加外场之间的关系,并探讨使用超导量子干涉仪探测封闭金属圆筒与球壳内表面氧化物的声核共振现象的可行性与优越性。最后,设计了一套使用超导量子干涉仪测量声核参量的实验方案。
This paper established enclosed cylinder and spherical Pb207 models to give formulas about acoustic nuclear dipole resonance detection of their inner surface oxide-massicot(β-Pb207O). Some calculations on the variations of SQUID-detected magnetic flux dependence of the mass of the metal oxide and the external magnetic field are done to study the feasibility and superiority of SQUID-detected ANR technique under metallic shield with inner surface oxidation. An experiment process was designed which can be used to detect ANR-related parameters using SQUID.
