Abstract

The hyperfine structure of the 8p 2 P 3/2 and2 P 1/2 levels of115In was measured using high-resolution laser spectroscopy on a collimated indium atomic beam. Step-wise excitations from the metastable 52 P 3/2 state via the shortlived 6s 2 S 1/2 state were employed. For the magnetic-dipole and electric-quadrupole interaction constantsa andb, respectively, the following results were obtained:a(8p 2 P 3/2)=16.3 (3) MHz,b(8p 2 P 3/2)=11 (3) MHz anda(8p 2 P 1/2)=44.0 (5) MHz. The magnetic hyperfine structure is shown to be strongly influenced by core polarization. For the electric-quadrupole moment of115In the valueQ=0.79 (20) barn is deduced.
