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.}, issn = {0031-9007}, doi = {10.1103/PhysRevLett.94.013201}, author = {Hancox, CI and Doret, SC and Hummon, MT and Krems, RV and Doyle, JM} }
