Lifetime Broadening and CI-Resonances Observed in ESCA

| Summary: | The electron spectrum of the
M
2
and
M
3
levels in bromine and krypton have been studied by high resolution ESCA. The
M
1
M
2,3
M
2,3
super Coster-Kronig transitions become energetically forbidden for
Z
less than sim-36 (Kr) and recent calculations therefore predict a decrease in the
M
2
and
M
3
natural linewidths around krypton in the periodic system. The experiment shows that the 3
p
3/2
linewidth is smaller in Kr than in Br. It is, however, also found that this decrease in linewidth is followed by configuration interaction (CI) between 3
p
2
P
and 3
d
2
nl

P
states. Several descrete CI resonances are observed in the Kr 3
p
spectrum. Such resonances are also studied in the
N
shell for the elements from Te (
Z
= 52) to Ba (
Z
= 56). For these elements the effect is found to be much larger due to the strong collective character of 4
d-nf
* excitations. |
