Abstract

The levels of 127Te have been studied with the 126Te(d, p)127Te reaction at 7.5 MeV bombarding energy using the MIT multiple-gap broad-range magnetic spectrograph. A total number of 154 levels was observed below 5.7 MeV excitation energy. The angular distributions of 47 of the emitted proton groups were compared with DWBA stripping calculations to determine the orbital angular momentum of the captured neutrons. Transition strengths (2J+1)Sln, j were extracted and compared to pairing-theory calculations. The total number of vacancies measured in the 1d52, 3s12, 1h112 and 2d32 states in the target is 6.0 , which is considerably lower than the expected value of 7.4 from pairing theory. It is suggested that this discrepancy results mainly from failure of the DWBA theory to predict the correct cross section for the ln = 5 transition.
