bull No information on unstretched E3

bull Larger data set required to determine if lt1-||E3||2+gt or lt1-||E3||4+gt vanish

bull Not definitive determination of collective mode dynamic (vibrational) or static (rotational) from Q3 alone

bull δE and Δix implies a coupling of an octupole phonon to the even-spin rotational band

bull Magnitude of Q3 consistent with dynamic picture similar to Q3(208Pb) and Q3(232Th)

bull Dynamic collectivity in 220Rn

Summary amp Outlook

See talk by George OrsquoNeill at 1545 today

bull Demonstrated sensitivity and ability to measure E3 matrix elements with Radioactive Ion Beams (RIBs)

bull B(E3 3- -gt 0+) measured for the first time in Rn and only second measurement in Ra both to ~10 precision

bull Experimental values rule out trend of cluster models

bull Exposes detailed differences in parameterisations of mean field calculations

bull Proposal for measurements in 222226228Ra and Ba region

bull Odd-mass nuclei key to atomic EDM measurements
