Abstract
Neon ions with energies ranging from 8 to 15 MeV have been obtained by the acceleration of doubly and triply charged ions in a 5.5-MV Van de Graaff. These projectiles have been used to study Coulomb excitation in 18 nuclei ranging from to . In particular, the levels of , , , , , , and were investigated. The spin of the 320-keV state of is uniquely assigned as and the mixing ratio, , is 0.52±.07. Strong evidence is found against previous assignments of for the spin of the 184-keV state in . The yields and angular distributions of the gamma rays require spin assignments of and ½ for the 184- and 93-keV states, respectively, in .
