摘要： We examine the characteristics of the π/2 pulse for simultaneously rotating two spin species of different gyromagnetic ratios with the same sign. For a π/2 pulse using a rotating magnetic field, we derive an equation relating the frequency and strength of the pulse to the gyromagnetic ratios of the two particles and the strength of the constant holding field. For a π/2 pulse using a linear oscillatory magnetic field, we obtain the solutions numerically, and compare them with the solutions for the rotating π/2 pulse. Application of this analysis to the specific case of rotating neutrons and 3He atoms simultaneously with a π/2 pulse, proposed for a neutron electric dipole moment experiment, is also presented. 出版者： United States: Elsevier B.V 出版日期： 2015-09-21 出處： Nuclear instruments & methods in physics research.
