Detailed sequential decay calculations that include both discrete states and unbound states in the continuum have been performed. Particular attention is paid to the lifetime of continuum states contributing to the process and to the role of the primary charge distribution. Comparisons to the recent data indicate temperatures greater than 7 MeV are model dependent and cannot be determined reliably. Furthermore, correct temperatures must be obtained from isotope yields via careful comparison with sequential decay calculations.
