Fig. 23 (a) Comparison of the 193 nm and 266 nm PES spectra of Au
10
produced using a 5%
Ar-He (
a
) or pure He (
d
) as carrier gases with those using 0.1% O
2
-He (
b
,
e
) and 0.5% O
2
-He
(
c
,
f
) as carrier gases. Note that the weak features (X
0
,X
00
,X
00 0
) are titrated out with increasing O
2
concentration. A-D are spectral features due to the D
3h
global minimum structure. (b) Calculated
minimum-energy structures for Au
10
(10A is the global minimum). Figures reproduced from
