Abstract
The Zeeman relaxation rate in cold collisions of Ti 3d(^2)4s(^2)(^3)3F2 with He is measured. We find that collisional transfer of angular momentum is dramatically suppressed due to the presence of the filled 4s^2 shell. The degree of electronic interaction anisotropy, which is responsible for Zeeman relaxation, is estimated to be about 200 times smaller in the Ti-He complex than in He complexes with typical non-S-state atoms.
