Abstract—The spectra of excited lithium-7 atoms prepared in a magneto-optical trap are studied using a UV laser. The laser diagnostics of the energy of Rydberg atoms is developed based on measurements of the change in resonance fluorescence intensity of ultracold atoms as the exciting UV radiation frequency passes through the Rydberg transition frequency. The energies of various nS configurations are obtained in a broad range of the principal quantum number n from 38 to 165. The values of the quantum defect and ionization energy obtained in experiments and predicted theoretically are discussed.

Abstract—A method of designing a thermonuclear reactor based on the modified Cockroft–Walton accelerator, where the lithium–proton fusion was first observed, is considered. It is proposed that the reactor have the form of a spherical capacitor with a point lithium cathode used as the inner electrode and a spherical anode, as the outer electrode. The interelectrode space is filled with hydrogen. A high-voltage electric pulse applied to the electrodes is used as a driver. The reactor parameters providing an ion temperature of 100 keV and a proton flux of 8.6 x 10^15 W/cm2to the cathode are determined. The basic elements of a system generating thermonuclear fusion energy, including those of the energy conversion chamber with a fusion chamber inside, are listed, and possible applications of the system are indicated.
