Atomic Beam Diode-Laser Spectroscopy
Combined with a collimated atomic beam source, diode laser without external cavity has been used as a spectroscopic light source to study atomic hyperfine structures and isotope shifts of Ba i. Spectroscopic measurements of the 6 s 2 1 S 0 – 6 s 6 p 3 P 1 transition of Ba i have been carried out. Al...

| Zusammenfassung: | Combined with a collimated atomic beam source, diode laser
without external cavity has been used as a spectroscopic light
source to study atomic hyperfine structures and isotope shifts of
Ba i.
Spectroscopic measurements of the 6
s

S
0
– 6
s

p

P
1
transition of Ba i have been carried out.
All hyperfine peaks of
135,137
Ba have been clearly seen
and resolution of 50 MHz has been attained.
Hyperfine constants
A
and
B
of the
3
P
1
state of
135,137
Ba have been determined.
Isotope shifts of stable Ba isotopes have also been measured.
From the measured isotope shifts, the 6
s
electron density at the
nucleus has been deduced to be 76.4(53) a.u. and
discussed in terms of the Hartree-Fock approximation. |
