    "abstract": "A method of fundamental solutions has been used to investigate transitions in\ntwo energy level systems with no level crossing in a real time. Compact\nformulas for transition probabilities have been found in their exact form as\nwell as in their adiabatic limit. No interference effects resulting from many\nlevel complex crossings as announced by Joye, Mileti and Pfister (Phys. Rev.\n{\\bf A44} 4280 (1991)) have been detected in either case. It is argued that\nthese results of this work are incorrect. However, some effects of Berry\u0027s\nphases are confirmed.",
