Fast ion collisions with small and large molecules have broadened the scope of atomic collision physics, its applicability towards astrochemistry and radiobiology. A news of ‘Mumbai getting proton machines for cancer therapy’- recently hit the newspaper(s). One needs to understand the concept of ionization, interference, energy loss, many body correlation in nucleo-bases, water or radio-sensitizer i.e. a nano-inserted DNA. The role of collective plasmon excitation, as observed in fullerene, Coronene (C24H12) and the e-emission enhancement in radio-sensitizers is commonly missed in models. The PAH molecules play an important role in astrochemistry. A recently developed highly charged ion accelerator-ECRIA and the existing Pelletron, along with a series of different spectrometers built in-house are being used push the boundary of the interdisciplinary field- meso-nano-bio systems. |
