Stopping power measurement for 19F, 24Mg, 27Al, 32S and 35Cl at energies ∼0.2 to ∼3.5 MeV/nucleon in Ti, Fe, Ni, Cu, Ag and Au

Multiple scattering and energy loss of fast heavy ions in thin solid targets

“…pdx where the empirical equation of Forster, Ward et al [16] for g is used. In Equation (8) the effective charge c 7 of the projectile in the target does not depend on target properties, whereas f is only a function of target parameters and of the projectile velocity v. Figure 6 illustrates the validity of the basic assumptions in Equations (7) and (8) …”

“…The uncertainty in the stopping power and the beam energy were also found to contribute appreciably to the systematic errors. The uncertainty in the measured stopping power is ±4% [25], contributing an uncertainty between ±4% and ±12% in the lifetimes. The uncertainty in the beam energy was ±0.2%, implying an uncertainty that varied with the transition but did not exceed ±11% of the lifetime values.…”

“…We opted for an empirical parametrization of experimental data on the stopping powers of Ne ions in Au [25]. A comparison was made between this parametrization and the stopping powers of SRIM [26].…”

Measurement of lifetimes inMg23

“…Second, the stopping power must be known to extract the lifetime. At the speeds relevant to the present study (β = 0.059-0.082) the energy loss of Mg ions in Au is dominated by electronic stopping, and the stopping powers have been determined experimentally by Forster et al [19] to a precision of ±4%. Approximately, dE/dx ≈ 8.5 MeV/μm.…”
