The lifetimes of the J~ = ~+ mirror states at Ex = 350.5+1.0 keV and 332-Β’-I keV in 2~Ne and 21Na, respectively, have been measured with the recoil-distance method. The two nuclei were produced by \*Β°Ne bombardment of a 2H gas target. The results are z = 224-3 ps and 14Β±3 ps for the states in ZlNe a
between the two extreme conformations of a keto and an eno form. The keto form is more stable in the gas phase and the eno form is believed to be more stable in solution. We show that the keto form can prevail in nonpolar solvents, but in polar solvents like chloroform, the eno form should be domina
