These include the speed plot, the time-delay method of Eisenbud and Wigner, the time-delay matrix of Smith, and a modification by Ohmura. Numerical results show a consistency not previously reported. One time delay method gives the most consistent results, supporting the conclusions of a recent theoretical study.11 pages, 4 figures. References to a recent study are modifiedNuclear Theorytext
