Role of incomplete fusion in production of 155 Tb

Production of 155 Tb radioisotope for medical purposes is still a challenge. In this regard the present study has been done using 16 O beam and 146 Nd target within the 3–7 MeV / nucleon energy range. The γ-ray spectrometry has been used to identify the residues produced in the reaction. The EF measurements have been done and cross-sections of 155 Tb have been reported and compared with the theoretical model code PACE 4. A strong indication of the occurrence of incomplete fusion has been realized within the energy range considered. The highest cross-section of 124 ± 12 mb has been obtained at E lab 101.7 ± 0.5 MeV.
