p electrons are 5, 6, 7, and 7, respectively. Config., configuration.
b The notation
J 1 ,
J 2 means that both
J values are equally probable, and
J 1 (
J 2 ) implies that the first is more probable.
c The isotope shift is the difference
238 U–

a The principal quantum numbers for the
f ,
d ,
s , and
p electrons are 5, 6, 7, and 7, respectively. Config., configuration.
b The notation
J 1 ,
J 2 means that both
J values are equally probable, and
J 1 (
J 2 ) implies that the first is more probable.
c The isotope shift is the difference
238 U–
234 U. A 1 means the value is supported by only one doublet. A star indicates that the value is converted from the
238 U–
235 U value. 1 mk = 0.001 cm
