J. Duprat et al., 1ST EVIDENCE OF THE MAGNETIC CHARACTER OF DIPOLE TRANSITIONS IN THE OBLATE BANDS OF PB-199, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 347(4), 1994, pp. 289-290
Internal conversion coefficients have been determined from on-line mea
surement of electron- and gamma-ray emission related to the dipole tra
nsitions in the so-called oblate collective bands in Pb-199. The resul
ts strongly support the M1 (or M1+E2) character of these transitions.
