Abstract
The Doppler-shift attenuation method was used to measure the lifetimes of nuclear levels formed in the heavy-ion bombardment of titanium deuteride targets. The nuclei formed are those resulting from the "inverse" () and () reactions, using beams of , , , , , and . Target backings of Mg, Al, and Cu were used as stopping media for the -decaying nuclei. rays were observed, mostly at 0° to the beam, with a 35- Ge(Li) detector. New results include mean lifetimes of 1.8±0.34 psec for the 811-keV level, 3.3±0.5 psec for the 1574-keV level, and 1.50±0.18 psec for the 2468-keV level of . The advantages and limitations of the method are discussed.
