A study of the temperature dependence of the energy spread and energy deficit of a Ge⁺⁺ ion beam produced by a liquid metal alloy ion source

This work involves an extensive study of the dependence on temperature (T) of the energy spread (ΔE_1/2) and potential energy deficit of the energy distribution of the Ge⁺⁺ beam produced by a liquid metal alloy ion source. The liquid metal alloy is Au₇₇Ge₁₄Si₉. Differences between consecutive sets of measurements were found but the energy spread versus temperature measurements agree remarkably well with a recent model that predicts ΔE_1/2 ∝ T^1/2. However, some questions involving the results either remain unresolved or are tentatively answered.
