Abstract
The Ne-20(p,r)Ne-18 reaction has been studied in order to investigate the p roperties of Ne-18 excited states. A missing 3(+) state of Ne-18, which cou ld have a great influence on the F-17(p,gamma)Ne-18 reaction rate, was sear ched for, but the existence of this state was not clearly verified. The spi ns and parities of the 5.11- and 5.15-MeV states were assigned tentatively by angular distribution measurements, as 2(+) and 3(-), respectively. We we re able to resolve the doublets at 4.5, 5.1, and 6.3 MeV clearly for the fi rst time due to our high precision system, which allowed us to determine th e widths of some critical states above the proton threshold of Ne-18 more p recisely.
