摘要：

The energy diagram of Mn-12-acetate is probed close to the top of the anisotropy barrier using a novel, high-sensitivity, electron paramagnetic resonance technique. Multiple resonances, and their temperature dependence, are observed from 35 to 115 GHz, for a single high-quality crystal. The data are sufficiently detailed to make extremely accurate comparisons with predictions based on a spin S = 10 Hamiltonian. Although overall agreement is good, we find evidence for possible inadequacies of this model.
