| Abstract: | Vibrational bands in226Ra were studied by Coulomb excitation and by the226Ra(d,pnγ) reaction. The first-excitedK π = 0+ and 1? bands with known band heads at 825 and 1049 keV, respectively, were extended up to the 8+ and 7? levels. A new 2+ level at 1110 keV and the known 2+ level at 1156 keV were observed following Coulomb excitation and interpreted asγ vibration and possible member of a second-exitedK π = 0+ band, respectively. TheE1 andE2 branching ratios from these vibrational bands to the ground and first-excited 0? band are explained within the rotational model including band mixings. No evidence was found for a 0+ level at 650 keV proposed earlier. |
