 | Wu, Yong-Shi | Algebraic solution for a two-level atom in radiation fields and the Freeman resonances | Using techniques of complex analysis in an algebraic approach, we solve the wave equation for a two-level atom interacting with a monochromatic light field exactly. A closed-form expression for the quasienergies is obtained, which shows that the Bloch-Siegert shift is always finite, regardless of ... | Bloch-Siegert shift; Freeman resonances; Quasienergies | 2006-02 |

 | Saam, Brian; Laicher, Gernot | Nuclear spin relaxation of 129Xe due to persistent xenon dimers | We have measured longitudinal nuclear relaxation rates of 129Xe in Xe-N2 mixtures at densities below 0.5 amagats in a magnetic field of 8.0 T. We find that intrinsic spin relaxation in this regime is principally due to fluctuations in the intramolecular spin-rotation (SR) and chemical-shift-anisot... | Nuclear spin relaxation; Xe129; Xenon dimmers | 2006-12 |
