El interés por la ecuación de Klein-Gordon con diferentes potenciales ha aumentado en los últimos años debido a su posible aplicaciones en Cosmología, Física de Hadrones y Física de Altas Energías. En este trabajo, investigamos las soluciones de la ecuación de Klein–Ecuación para bosones bajo la influencia de un potencial externo utilizando el método de Feshbach-Villars. Presentamos resultados detallados en dos casos: el potencial de Coulomb y el potencial armónico. Para el segundo caso, estudiamos los efectos de la auto-interacción de partículas dentro de una aproximación de de campo medio. Mostramos que nuestros resultados convergen suavemente a la solución de la ecuación de Schrödinger para los mismos sistemas a medida que disminuyen los...
