Remarks on excited states of even-even nuclei and on the existence of a complex vibrational second excited states

Abstract

Se discuten diferentes tipos de espectros en núcleos pares-pares, Las propiedades de esos núcleos para 40 < A < 154 y 180 < A < 222 son resumido. Varias predicciones teóricas de la existencia de un complejo vibracional segundo estado excitado se describen y comparan con datos experimentales. Different types of spectra in even-even nuclei are discussed, Properties of those nuclei for 40 < A < 154 and 180 < A < 222 are summarized. Several theoretical predictions of the existence of a com plex vibrational second excited State are described and compared with experimental data.
