Title: (t,. cap alpha. ) reaction on actinide nuclei and the observation of /sup 243/Np

Abstract

The (t,..cap alpha..) reaction has been carried out on the actinide targets /sup 234/U and /sup 244/Pu using a 17 MeV beam of 80% polarized tritons. The residual nucleus /sup 233/Pa has been previously studied and serves to calibrate the trends of the analyzing power for known spin states. Twenty-two energy levels were observed in /sup 243/Np, a nucleus previously unreported, and a number of spin assignments are suggested. The observed analyzing powers are very similar to those previously measured in the lead nuclei, permitting the use of empirical spin determinations over a wide range of nuclei.
