T. Weber et al., STUDY OF THE FIRST-EXCITED K-PI=0(-228 IN THE RA-226(ALPHA, 2N) REACTION() AND 2(+) BANDS IN TH), EUROPEAN PHYSICAL JOURNAL A-HADRONS AND NUCLEI, 1(1), 1998, pp. 39-44
Excited bands of Th-228 were studied in the Ra-226(alpha, 2n) reaction
by gamma-ray and conversion-electron spectroscopy. The first-excited
K-pi = 0(+) and 2(+) bands were identified up to I-pi = 12(+) and 10(), respectively. The spin dependence of the moments of inertia is disc
ussed. The experimental data indicate a structural change of these ban
ds from Th-228 to Th-230 and Th-232.
