Conversion-electron spectroscopy in the decay of superdeformed 135 Nd

We have investigated the structure of the superdeformed band in 135 Nd using conversion-electron spectroscopy. The transitions within the superdeformed band show conversion coefficients which are consistent with an E2 multipolarity. From the conversion coefficients of transitions linking this band with known low-lying states its positive parity was established. Hence, a direct determination of the parity of a high-spin superdeformed band could be performed for the first time.
