## Description

Title of program: ROTATION MATRIX ELEMENTS DD Catalogue Id: AABI_v2_0 [AAFG] Nature of problem The reduced matrix elements of rotation operators are calculated. The sum is done for all the values for which the argument of the factorials are greater than or equal to zero. Each matrix element is written explicitly as a literal polynomial on the variables cos (beta/2) and sin (beta/2). Versions of this program held in the CPC repository in Mendeley Data AABI_v1_0; ROTATION MATRIX ELEMENTS D; 10.1016/0010-4655(85)90124-9 AABI_v2_0; ROTATION MATRIX ELEMENTS DD; 10.1016/0010-4655(86)90139-6 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
