LIFETIMES OF THE LOW-LYING LEVELS OF 20Ne

Abstract
The lifetimes of the 1.63-, 4.25-, 4.97-, and 5.63-MeV levels in 20Ne have been measured by the Doppler shift attenuation method. The lifetimes in picoseconds are 1.23 ± 0.12, 0.134 ± 0.012, , 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 , , , and .
