Inclusive measurements of light charged particles emitted in the reaction40Ar+27Alat

Correlation functions of light charged particles from projectile-like fragment source in and 77 MeV 40Ar + 27Al collisions

“…This adds an important and novel piece of information to the picture of the reaction mechanism emerging from previous studies [17,18].…”

“…This may be expected, since the Coulomb push per particle experienced by an α-particle is less than half that experienced by a proton (taking into account the mass and charge of the α-particle, and its larger average emission distance due to its larger size). In addition, the kinematical focusing at forward angles increases with the mass of the emitted particles, and it is strongest for α-particles [17]. Another effect for the smearing the dumb-bell structure may come from recoil effects.…”

“…Speculations on the origin of these copious α-particles have been discussed in Refs. [17,18]. It could be due to the production in the reaction of excited light ions, and/or to the α structure of the two interacting nuclei [25].…”

“…In particular, this is true for the reverse kinematics reaction Ar + Al, investigated by several authors [8][9][10][11][12][13][14][15][16][17][18]. In this paper, we aim to study light charged particle (LCP) emission from the PLF, in E/A = 44 and 77 MeV 40 Ar + 27 Al collisions.…”

“…[17]). In the present study, the experimental conditions of low detection thresholds, large dynamic range, fine granularity, and small angular separation between the centers of adjacent detectors, allows us to perform the correlation function analysis in a very forward angular range, 0.7 o ≤ θ lab ≤ 7 o .…”
