The new isotope /sup 53/Ti has been produced with the /sup 48/Ca(/sup 7/Li,pn)/sup 53/Ti reaction at E/sub /sub 7/Li/ = 14--20 MeV. The ..beta..-decay scheme of /sup 53/Ti was determined from ..gamma..-ray singles and ..gamma..--..gamma.. coincidence experiments by using high-resolution Ge(Li) and intrinsic germanium detectors. The four strongest decay ..gamma.. rays have energies of 100.8, 127.6, 228.4 (all+-0.1), and 1675.5+-0.3 keV, with relative intensities of 50.90+-2.7, 115.4+-12.0, 100, and 62.5+-6.7, respectively. The /sup 53/Ti half-life was determined to be 32.7+-0.9 sec. Three new levels with excitation energies of 1958, 2550, and 2931 keV were observed in the daughter /sup 53/V. The total /sup 53/Ti decay energy of 5.02+-0.10 MeV was measured by performing a ..beta..--..gamma.. coincidence experiment using a plastic scintillation detector for the ..beta.. rays. This yields a /sup 53/Ti mass excess of -46.84+-0.10 MeV. The decay scheme provides J/sup ..pi../ restrictions for the observed states of /sup 53/V, and these are compared with previous measurements and shell model calculations. The measured mass of /sup 53/Ti is compared with various predictions.
