For large inertial confinement fusion deuterium‐tritium targets, a way to diagnose α slowing might be via capture reaction γ rays. Calculations are presented for two such methods: one uses the α+T direct capture γ rays, the other is based on a series of resonant α‐capture reactions. For small targets (ρR≤0.02 g/cm2), the total α+T γ‐ray yield relative to the DT neutron yield is temperature independent and proportional to the ρR value. For large targets (ρR≥0.2 g/cm2), this quantity becomes temperature dependent and ρR independent. Some experimental aspects are discussed.
