Superdeformed bands and ‘shears’ bands in 197Pb and 198Pb

  • Published:
Zeitschrift für Physik A Hadrons and nuclei

Abstract

Excited states in 197Pb and 198Pb, produced in the 186W (18O,xn) reaction, were studied using the EUROGAM phase 2 γ ray spectrometer array. Two new superdeformed bands have been observed in 197Pb, and the existence of a superdeformed band in 198Pb has been confirmed. The increased statistics provided by the latest generation of arrays has resulted in the reordering of some of the previous known cascades of magnetic dipole transitions, with the first observation of the extremely weak E2 crossover transitions.
