Suppression of Angular Momentum Transfer in Cold Collisions of Transition Metal Atoms in Ground States with Nonzero Orbital Angular Momentum. Physical Review Letters 94, no. 1. doi:10.1103/physrevlett.94.013201. http://dx.doi.org/10.1103/PhysRevLett.94.013201.0031-9007https://nrs.harvard.edu/URN-3:HUL.INSTREPOS:37376595The 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.en-USGeneral Physics and AstronomySuppression of Angular Momentum Transfer in Cold Collisions of Transition Metal Atoms in Ground States with Nonzero Orbital Angular MomentumJournal Article2023-07-2510.1103/PhysRevLett.94.013201
