Stopping power of helium gas for 9Be ions from 2 to 31MeV

GARFIELD + RCo digital upgrade: A modern set-up for mass and charge identification of heavy-ion reaction products

“…The overall quality of the detector response (namely mass, energy and position determination) is tested by an example of Q-value estimation from a 3-body event reconstruction [51]. Indeed in a recent experiment [28] performed with GARFIELD + RCo, the Q-values of a specific reaction, i.e.…”

“…Especially for the low energy region of the heavier fragment, the "in gas" energy loss corrections, estimated according to Refs. [50,51] have to be considered. The high quality of the detectors and electronics can be demonstrated by the wide range of charge identified ions: as shown in Fig.…”

“…These calculations were then fitted with a polynomial function such that for every detected α particle it was possible to calculate the energy upon emission in the reaction and hence the center-of-mass energy. The energy-loss calculations provided an accurate determination of the energies of known resonances in 13 C, whereas it is known that other energy-loss calculations are less accurate [8]. In the current analysis it was assumed that the influence of the beam on the gas properties was negligible given the significant heat capacity of the gas.…”

Studies on Energy Loss, Range and Straggling of Light Ions in Polymer (Pmma) Film

“…As a result, this leads to a lesser energy loss of alpha particles in the medium. Consequently, the transmitted energy of alpha particles is high at higher pressure but whereas at lower pressure the transmitted energy is less [12][13][14][15][16][17]. This is due to the more number of molecules present in the scattering chamber and that result in the probability of interaction of the alpha particles with these molecules is higher and that gives the lesser transmitted energy.…”
