The time-stamp structure of the digital data acquisition system of the Indian National Gamma Array (INGA) has been utilized to carry out prompt-delayed coincidence technique for the spectroscopic study of fission fragments. This technique was found to be useful to determine the states above the long-lived isomer (with half-life up to $\sim$5 𝜇s), present in the fission fragments. The angular correlation of 𝛾-rays, emitted by the fission fragments, has also been used in the present INGA geometry to determine the spins of the de-exciting states.
