1 IntroductionThe time differential perturbed angular correlation(TDPAC) has been known for about 50 years. 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 nucleus
