NEW HIGH-SPIN LEVELS IN 20Ne

Abstract

Levels of ²⁰Ne at excitation energies of 10.57, 12.19, and 13.39 MeV have been formed in the ¹²C(¹²C, α)²⁰Ne reaction. Angular correlations of deexciting alpha particles have been measured, leading to spin and parity assignments of 4+, 6 +, and 7−, respectively. Level energy systematics and systematics of reduced alpha-particle widths suggest that these levels be associated with rotational bands.
