Preequilibrium α emission from ¹⁴N-induced reactions on various heavy targets has been studied to derive local nuclear temperature involved in the hot-spot model. The resultant values of temperature after subtracting the equilibrium value fall almost exponentially with the increasing emission angles in all cases, from which we obtain 1.8×10⁻²¹ sec as the nuclear relaxation time.
