PARTIAL-WAVE ANALYSIS FOR CERTAIN SIMPLE SYSTEMS WITH APPLICATION TO REACTION O-16(D, ALPHA1) N-14

The angular distributions of spin-zero even-parity particles emerging from a compound nucleus formed by a 1+ and 0+ pair are displayed in a simple form which facilitates parametrizing the differential cross section in terms of partial waves. The method is applied to the O16(d,α1)N*14 data of Jobst et al. to display the resonant partial waves corresponding to F18 states. Intrinsically ambiguous solutions of number 2lmax are found empirically. The problem of selecting the correct solution is discussed. Data with polarized deuterons are of no help since the analyzing powers are energy-independent (cf. Jacobsohn and Ryndin, who first noted that the reaction is an absolute detector of deuteron alignment). © 1969 The American Physical Society.
