Abstract : The lifetimes of the 1.63-, 4.25-, 4.97-, and 5.63-MeV levels in Ne 20 have been measured by the Doppler shift attenuation method. The lifetimes in picoseconds are 1.23=0.12, 0.134=0.012, 4.8+1.7 or - 1.1, and 0.35=0.075 respectively. The reduced widths in Weisskopf units for the 1.63-, 2.62-, 3.34-, and 4.00-MeV gamma-ray transitions, together with the gamma-ray multipolarities, are 17.6+1.9 or -1.5 (E2), 15.1+1.5 or -1.2 (E2), 7.4+2.1 or -1.9 x 0.000001 (E1), and 4.7+1.3 or -0.8 x 0.000001 (E1).
