Abstract
The energy spectrum of α-particles has been measured for the system22Ne+197Au atE 1ab=178 MeV. The reaction products emitted at 0° relative to the beam direction are analysed using a magnetic spectrometer and detected by means of a semiconductorΔE−E telescope. The measured α-particle spectrum strongly differs from the one expected from evaporation. The experimentally measured maximum α-particle energy almost amounts to the maximum possible value calculated from the reaction energy balance. The obtained results are discussed from the point of view of the mechanism of formation of high-energy α-particles.
