Carrier-free was thermally separated from proton-irradiated . Pressed targets were irradiated with protons at the IP2 beamline of the high-intensity proton accelerator facility at the Paul Scherrer Institute. The well-known thermal decomposition of at C and the strong adsorption of on a surface allowed for a simple and quantitative gas-phase separation of carrier-free from bulk amounts of target material between 550 and °C. The separation efficiency was verified by -spectroscopy the main -emissions of and co-produced . This method generally provides a fast and reliable preparation of carrier-free, neutron-deficient radioisotopes (e.g., medically relevant ) from a proton-irradiated matrix.
无载体的[物质名称]通过热分离法从质子辐照的[物质名称]中分离出来。压制的靶材在保罗·谢尔研究所高强度质子加速器设施的IP2束流线用质子进行辐照。[物质名称]在[温度]℃时众所周知的热分解以及[物质名称]在[物质名称]表面的强吸附作用，使得在550至[温度]℃之间能够从大量的靶材中对无载体的[物质名称]进行简单且定量的气相分离。通过[光谱名称]光谱法对[物质名称]和共产生的[物质名称]的主要[发射名称]发射进行分析，验证了分离效率。该方法通常能从质子辐照的[基体名称]基体中快速且可靠地制备无载体、缺中子的[放射性同位素名称]放射性同位素（例如，与医学相关的[物质名称]）。
