The single gamma-ray spectra of207Bi were measured with 32 c. c. Ge(Li) detector. Evidence of gamma transitions of energies 1·440 MeV and 1·460 MeV is found. The relative intensity of these lines has also been estimated by measuring their photopeak areas. There is no evidence of the weak 0·9 MeV gamma as reported earlier (Alburger D. E.,Sunyar A. W., Phys. Rev.99 (1955), 695;Jar Dine L. J., Phys. Rev.C 11 (1975), 1385).
