TEMPERATURE DEPENDENCE OF EXCITATION TRANSFER RATE CONSTANTS FOR HE(23S1)+NE-]HE+NE(2S) AND HE(21S0)+NE-]HE+NE(3S)

A temperature dependence of the form K=K0 exp (-E/kT) has been observed for the rate constants for excitation transfer from the helium metastable atoms to neon. For He(23S)+Ne→He+Ne(2s), K 0=3.3×10-11 cm3/sec and E=0.051 eV. For He(21S)+Ne→He+Ne(3s), K0=2.1×10-10 cm3/sec and E=0.041 eV. © 1969 The American Institute of Physics.
