Title: Atomic and nuclear polarization of /sup 12/C, /sup 13/C, and /sup 15/N by beam-foil interaction at 300--400 keV

Abstract

Induced nuclear spin polarization P by hyperfine interaction following passage of 0.5 ..mu..A 300--keV beams of /sup 12/C/sup +/, /sup 13/C/sup +/, and /sup 15/N/sup +/ through single tilted carbon foils yields Vertical BarPVertical Bar = (0.4 +- 0.8)%, (3.2 +- 0.6)%, and (5.7 +- 0.9)%, respectively. The nuclear polarizations were enhanced by passage through two tilted foils, and the sign of the polarization flipped by a simple flip of the foil direction with respect to the beam direction. From quantum-beat measurements with circularly polarized light, experimental quantum beat frequencies ..omega.. = 6790 +- 570 and 747 +- 62 MHz for the unresolved 6578--6583 A doublet in CII, and ..omega..(5667 A) = 2860 +- 240, ..omega..(5680 A) = 4810 +- 40 MHz in NII are determined.
