Este artículo investiga el efecto de niveles cercanos no resonantes en las líneas espectrales de los átomos que interactúan con un campo electromagnético. Específicamente, examinamos el efecto AC Stark que ocurre cuando la frecuencia del campo coincide con la frecuencia de transición entre dos niveles más bajos y el campo tiene un número promedio pequeño de fotones (|α| 2 < 4). Nuestra investigación demuestra que los cambios en la forma de la línea espectral se pueden utilizar para distinguir entre los estados de gato de Schrödinger con fases opuestas en π, a saber, los estados |αi + |−αi y |αi − |−αi. Descriptores: Estados gato de Schrödinger; efecto AC stark; formas de las líneas; espectrales, modelo de Jaynes-Cummings.
This article investigates the effect of near non-resonant levels on the spectral lines of atoms interacting with an electromagnetic field. Specifically, we examine the AC Stark effect that occurs when the field frequency matches the transition frequency between two lower levels and the field has a small average number of photons (|α| 2 < 4). Our research demonstrates that the changes in spectral line shape can be used to distinguish between Schrödinger cat states with opposite phases in π, namely, the states |αi + |−αi and |αi − |−αi.
