ScholarBank@NUS Repository. | Abstract: | In this study, it was predicted that subthermal line shapes should appear in high-resolution photoassociation spectra of the 1∏g state of Ca dimer near the 1←1S laser-cooling transitions. It was shown that subthermal linewidth of scattering resonances are possible when the contributions to the line shape from the relevant S-matrix elements is restricted to very low collision energies below the range of thermal energies kBT. | Source Title: | Physical Review A.
