Observation of band structure and new isomeric levels in ²⁰⁴At

Nuclear structure of proton-rich trans-Lead region of nuclear chart largely remains unexplored because of the difficulty in producing these nuclei by fusion-evaporation reactions by avoiding large background contamination due to stronger and competing fission reaction channel, and the difficulty in extracting the targeted information and corroborating the results from the theoretical shell model calculations, which are virtually impossible to perform for these nuclei. High spins states of neutron deficient ^208,210Fr nuclei were investigated in the earlier campaigns of the INGA facility
