Statistical emission of deuterons and tritons from highly excited compound nuclei.

Statistical model calculations, employing optical model transmission coefficients for particle emission, have been able to describe in a satisfactory way n, p, d, t, and a emission properties of compound nuclei at excitation energies below 100 MeV. Recent experimental data have shown that the same model systematically overpredicts the deuteron and triton yields observed at higher excitation energies up to 405 MeV. The predictions of the statistical model with transmission coefficients derived from an ingoing-
