title: Spin dependence of optical dephasing in ruby: the frozen core.
abstract: Measurements of the (4)A(2)(-3/2) ? E(-(1/2)) optical dephasing time in ruby are obtained for the first reported time and compared with the previously studied (4)A(2)(-(1/2)) ? E(-(1/2)) transition. Frozen-core effects reduce the ratio of dephasing times T(2)(-(1/2))/T(2)(-3/2) to 1.5 from the value 7.6 expected from a simple magnetic tuning rate consideration.
