Abstract

States in 20Ne have been studied through the 12C( 14N, 6Li) 20Ne reaction. Excitation functions have been measured from 20 MeV to 60 MeV in steps of 5 MeV at different angles for 20Ne states up to 10 MeV excitation energy. States of 24Mg have been also populated using the 12C( 14N, d) 24Mg reaction; excitation functions of 24Mg states up to 9 MeV excitation energies as well as angular distributions at 35 MeV bombarding energy have been obtained. Comparisons of data with Hauser-Feshbach calculations show clearly that the compound nucleus mechanism is the main process for both 12C( 14N, 6Li) 20Ne and 12C( 14N, d) 24Mg reactions. Strong evidence has been provided for inhibition of the 26Al compound nucleus formation for angular momenta higher than critical values. The location of the yrast line in the 26Al nucleus is discussed.
