So far, no on-line TDPAC(TDPACOL) has been performed because of mother nuclei all having a rather long lifetime. In addition, almost all TDPAC experiments have been conducted using probe nuclei with a mass heavier than 40.The present work is motivated to develop a TDPACOL technique with light probe nuclei. The key point for it is to have short-lived mother nuclei with a lifetime of, say, several ten seconds. We have found a suitable mother nucleus 19O having a half-life of 26.9 s and decaying to the daughter 关 键 词：NUCLEI NUCLEUS mother LIFETIME ANGULAR NUCLEUS Correlation DAUGHTER motivated PROBE
