1958年11月15日至1958年10月物理评论第1卷，精细能级，总角动量值为F= 5/2、3/2和1/2。观察到了所有的塞曼跃迁（DEW，AmE=+ 1）和所有的m个超精细跃迁（hF=+ 1，&mF=+ 1）。典型的谐振曲线如图1所示.共振的半宽约为4 kc/sec。各种超精细跃迁的识别是通过观察它们的场依赖性来实现的。在所有情况下，所观察到的场依赖性同意在1%以内的氮共振的理论值。对于（5/2-3/2）和（3/2-1/2）间隔获得的值是v1，v2 = 26。1275&0。0005百万次/秒，v>> 0.5，= 15。6772+ 0。0005兆周/秒。这些值包括塞曼曲率的小修正（通常为1千周/秒）。通过观察压力降低两倍时的超精细转变之一，对可能的压力变化进行了搜索。已经确定，如果存在压力偏移，则在所研究的压力范围内，压力偏移小于1 kc/sec。所引用的不确定性约为可能误差的三倍，旨在考虑到小的压力变化的可能性。
VOLUME 1,+ UMBER 10 PHYSICAL REVIE%'LETTERS NovKMBER 15~ 1958 fine levels having total angular momentum values of F= 5/2, 3/2, and 1/2. All of the Zeeman trans-itions (DEW, AmE=+ 1) and all of the m hyperfine transitions (hF=+ 1, &mF=+ 1) have been observed. Typical resonance curves are shown in Fig, 1. The resonances have a half-width of about 4 kc/sec. The identification of the various hyperfine transitions was facilitated by observa-tion of their field dependence. In all cases the observed field dependence agreed within 1% with the theoretical values for the nitrogen resonances. The values obtained for the (5/2-3/2) and the (3/2-1/2) intervals are v&,»= 26. 1275&0. 0005 Mc/sec, v» &,= 15. 6772+ 0. 0005 Mc/sec.These valuesinclude a small correction for Zeeman curvature (typically 1 kc/sec). A search was made for a possible pressure shift by observing one of the hyperfine transitions as the pressure was reduced by a factor of two. It was established that if a pressure shift exists, it is less than 1 kc/sec over the range of press-ures studied. The quoted uncertainties are about three times the probable error and are intended to allow for the possibility of a small pressure shift.
