- Resonance scattering of light as function of magnetic field has been used to investigate the hyperfine structure of the 4p2P3/2- and 5p2P3/2-terms in the potassiumI-spectrum, using a sample enriched in the K40-isotope. With increasing magnetic field strength a structure containing two characteristic signals for K40 was observed. Taking into account the small ratio of hyperfine structure splitting to radiation width, these signals could be interpreted as an overlapping of three level-crossings. The line shape and magnetic field strength of these signals can be understood by taking for the magnetic interaction constantsA40(4p2P3/2)=(-7.59±0.06) Mc/s,A40(5p2P3/2)=(-2.45±0.02) Mc/s and the electric quadrupol coupling constantsB40(4p2P3/2)=(- 3.5 ±0.5) Mc/s,B40(5p2P3/2)=(-1.1± 0.2) Mc/s usinggJ=4/3. The values ofB/A yield withSternheimer corrections for the nuclear electric quadrupolmomentQ(K40=-0.07 · 10-24 cm2.

- The level crossing method has been used for the investigation of the hyperfine structure of the 6p2P3/2 and 7p2P3/2 levels of the isotopes Cs133, Cs135, and Cs137. For the hyperfine coupling constants a and b and for the lifetimes ? we find: a(6p Cs133)=50.72(3) gJ/-1.345, b(6p Cs133)=-0.38(18) gJ/-1.345 a(7p Cs133)=16.610(6) gJ/-1.3349, b(7p Cs133)=-0.15(3) gJ/-1.3349 a(6p Cs135)=53.64(4) gJ/-1.345, b(6p Cs135)=7.41(32) gJ/-1.345 a(7p Cs135)=17.570(6) gJ/-1.3349, b(7p Cs135)=2.35(7) gJ/-1.3349 a(6p Cs137)=55.80(4) gJ/-1.345, b(6p Cs137)=7.54(20) gJ/-1.345 a(7p Cs137)=18.274(6) gJ/-1.3349, b(7p Cs137)=2.37(4) gJ/-1.3349 (MHz), ?(6p2P3/2)=29.7(2) -1.345/gJ ns, ?(7p2P3/2)=135(1) -1.3349Jns.
