mJ Mixing in Oriented 4P122 Potassium Atoms, Induced by Collisions with Inert Gases

W. Berdowski, L. Krause

A modified Zeeman scanning method was used to excite selectively the magnetic substates of the $4^{2}P_{\frac{1}{2}}$ potassium atoms mixed with inert gases and placed in a strong magnetic field. The resulting potassium-inert-gas atomic collisions induced ${m}_{J}$ mixing in potassium, which manifested itself by the depolarization of the potassium resonance fluorescence. The polarization measurements yielded the following disorientation cross sections: K-He: 46 ${\mathrm{\AA{}}}^{2}$ ; K-Ne: 39 ${\mathrm{\AA{}}}^{2}$ ; K-A: 52 ${\mathrm{\AA{}}}^{2}$ ; K-Kr: 80 ${\mathrm{\AA{}}}^{2}$ ; K-Xe: 107 ${\mathrm{\AA{}}}^{2}$ .A modified Zeeman scanning method was used to excite selectively the magnetic substates of the $4^{2}P_{\frac{1}{2}}$ potassium atoms mixed with inert gases and placed in a strong magnetic field.

mJ Mixing in Oriented 4P322 Potassium Atoms Induced by Collisions with Inert Gases

W. Berdowski, T. Shiner, L. Krause

The cross sections for the decay of circular and of linear polarization in oriented $4^{2}P_{\frac{3}{2}}$ potassium atoms, induced in collision with inert-gas atoms, were determined in a series of fluorescence experiments. A modified Zeeman scanning method was used to populate selectively the ${m}_{J}$ sublevels of the $^{2}P_{\frac{3}{2}}$ potassium atoms mixed with inert gases and placed in a strong magnetic field. Measurements of depolarization of the fluorescence, in relation to gas pressures, yielded the following depolarization cross sections: ${\ensuremath{\sigma}}_{1}$ (disorientation): K-He, 86 ${\mathrm{\AA{}}}^{2}$ ; K-Ne, 86 ${\mathrm{\AA{}}}^{2}$ ; K-Ar, 164 ${\mathrm{\AA{}}}^{2}$ ; K-Kr, 248 ${\mathrm{\AA{}}}^{2}$ ; K-Xe, 251 \AA{}. ${\ensuremath{\sigma}}_{2}$ (disalignment): K-He, 127 \AA{}; K-Ne, 120 ${\mathrm{\AA{}}}^{2}$ ; K-Ar, 240 ${\mathrm{\AA{}}}^{2}$ , K-Kr, 301 ${\mathrm{\AA{}}}^{2}$ , K-Xe, 336 ${\mathrm{\AA{}}}^{2}$ .
