Raman spectroscopy is widely used to study the phonons in solids, liquids and gases. Our micro-Raman spectrometer has been extensively used by many researchers across the country for characterization of nano particles, films, solids, liquids and identifying different phases and to elucidate physical phenomena like, spin-phonon, electron-phonon, orbital-lattice interactions and phase transitions. The results from this system contributed in nearly 150 publications in international journals.

The group is primarily pursuing and supporting nuclear structure studies through in-beam gamma-ray spectroscopy based on large detector arrays. One of the salient facilities used for the purpose is the Indian National Gamma Array (INGA) set up by turn at different accelerator Centres in the country. The group is one of the principal contributors of the resources, instrumentation and data processing/analysis software used in the INGA campaigns. The group has led the development and implementation of a digitizer based pulse processing electronics and data acquisition system used in INGA. The group has developed a set of programs processing and characterizing data acquired from such systems. These developments are used by the user community in the universities and institutes across the country. The group has also developed programs for nuclear level lifetime analysis using Doppler Shape Attenuation Method (DSAM), extending the applicability of the same to unconventional experimental setups such as those using thick molecular targets. The group is involved in large basis shell model calculations using the high performance computing facility at the Centre.
