    "abstract": "The experimental observation of effects due to Berry\u0027s phase in quantum\nsystems is certainly one of the most impressive demonstrations of the\ncorrectness of the superposition principle in quantum mechanics. Since Berry\u0027s\noriginal paper in 1984, the spin 1/2 coupled with rotating external magnetic\nfield has been one of the most studied models where those phases appear. We\nalso consider a special case of this soluble model. A detailed analysis of the\ncoupled differential equations and comparison with exact results teach us why\nthe usual procedure (of neglecting nondiagonal terms) is mathematically sound.",
