Electron-photon angular correlations for the excitation of krypton by electron impact

Abstract

Angular correlation parameters lambda , chi and epsilon for the 5s(3/2)10 3P1 and 5s'(1/2)10 1P1 states of Kr have been measured with an electron-photon coincidence technique at incident electron energies of 40, 50, 60 and 80 eV. These parameters were determined from two independent angular correlation measurements. The results are compared with the previous experimental and theoretical results.
