The gamma rays following thermal neutron capture in titanium have been studied with two high resolution spectrometers and with an angular correlation arrangement using two sodium iodide scintillation spectrometers. The high resolution instruments were a pair spectrometer for the energy range 2.8 to 11.0 Mev and a double flat crystal diffraction spectrometer for the energy range 0.14 to 5 Mev. A total of 54 gamma rays were observed, 25 of which had not previously been resolved. A decay scheme for Ti/sup 49/ is given with energy levels at 1.375 plus or minus 0.001, 1.583 plus or minus 0.001, 1.719 plus or minus 0.001, 3.172 plus or minus 0.002, and 3.261 plus or minus 0.005 Mev. The neutron binding energy of Ti/sup 49/ is concluded to be 8.132 plus or minus 0.006 Mev. Angular correlation measurements were made between some of the prominent gamma rays emitted in the decay of Ti/sup 49/. The measurements confirm that the spins of the 1.378 and 1.719 Mev levels are 3/2 and 1/2, respectively. (auth)
