| Abstract | The work presented here is on the study of energy levels and transitions in the 115In nucleus produced in, - decay of 115mCd with halflife of 44.6 d. The gamma singles spectra have been measured, applying modern techniques in gamma spectroscopy. The detection system consisted of germanium GMX–Ge detector and conventional low noise electronics connected to a multi-channel analyzer. The energies and relative intensities of observed gamma transitions were determined. Actual of nineteen gamma transitions in 115 In nucleus following the decay of 115mCd are reported. Two lines, 605 KeV and 889.08 KeV are observed for the first time. A level scheme of ten levels to the 115In nucleus, is constructed .The spin for the level 1418.27 KeV has been confirmed to be 9/2. The logft values of the beta transitions feeding levels in 115In have been calculated. These values together with the corresponding gamma transitions intensities were used to confirm the spins and parities of different levels which were found to agree with previously reported values. |
