α-particle emission in the reaction 48Ca+Ta at Coulomb energy

Abstract

Inclusive energy spectra have been measured for light charged particles emitted in the bombardment of Ta target by 48Ca ions at 261 MeV and 471 MeV. The reaction products were analyzed and detected by means of a ( ∆E × E ) telescope placed in the focal plane of a magnetic spectrometer located at forward angles with respect to the beam direction. In all the reactions studied light charged particles with an energy close to the respective calculated kinematic limit for a two-body exit channel are produced with relatively great probability. The results obtained make it possible to draw some conclusions about the reaction mechanism involving the emission of light charged particles.
