Abstract

Applying a modified quantum beat method, the hyperfine splittings of 14NIII 2p 2P3/2 are determined to ν 3/2,5/2 = (252.0 ± 1.1) MHz and ν1/2,3/2 = (126.2 ± 0.4) MHz. From the frequencies we deduce the nuclear electric quadrupole moment of 14N Q (14N) = (19.4 ± 0.9) mb and the quadrupole coupling constant for the 2p-electron in 14NIII 1s22s 22p 2P3/2 : e Q qat = - (16-6 ± 0.6) MHz
