We describe theoretical and experimental investigations of steady-state gain without population inversion that can occur on the ${\mathit{D}}_{1}$ transition of potassium, upon strong cw-laser excitation of the ${\mathit{D}}_{2}$ transition. A Raman-

We report steady-state gain due to coherence effects in a potassium-helium mixture, for strong pumping near the ${\mathit{D}}_{2}$ line and probing near the ${\mathit{D}}_{1}$ line. The absorption-gain spectra are in good agreement with a four-level

Light‐controlled deposition of potassium atoms onto a glass surface by light‐induced drift (LID) is demonstrated. The collection of atoms by wave‐front curvature is found to be important for maximizing the deposition rate. The light control of

Summary This study examined the effects of a nonverbally warm versus a nonverbally neutral impersonal teaching style on the learning, question answering, and question asking of 20 white and 20 Eskimo students. Each student attended both a warm and a

The furor unleashed by Jensen's (1969) suggestion of a genetic explanation for the lower performance of Blacks on intelligence tests has led to substantial doubt about the social value of research on racial differences in cognitive abilities. Using t
