Heavy-ion beam induced effects in enriched gadolinium target films prepared by molecular plating

The process of molecular plating and the characteristics of the produced thin films – What we have learned in 60 years and what is still unknown

“…With SEM, energy-dispersive X-ray spectroscopy (EDS) was also employed early on to determine the elemental composition of the thin films. [13,15,19,26]. However, these methods are all unable to provide information on the chemical composition of the thin films, which is why spectroscopic methods, like IR, Raman, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), or ion beam spectroscopy like elastic recoil detection analysis (ERDA), Rutherford backscattering (RBS) or proton-induced X-ray emission (PIXE), were also used later [2,13,15,16,19,[27][28][29].…”

“…Two primary beam energies were used in the experiment; initially, the cyclotron produced a laboratory-frame beam energy of Reactions of 44 Ca projectiles with targets of 160 Gd2O3, 157 Gd2O3, 156 Gd2O3, and 154 Gd2O3 were studied in the experiment. The targets were prepared in-house using the molecular plating method [19][20][21]. Starting material for the 156 Gd2O3 target was purchased from Isoflex as an oxide powder with an enrichment greater than 95.4%.…”

“…Approximately 1 mg of the starting material was dissolved in 0.1 or 2 M HNO3 and evaporated to dryness under Ar gas. The resulting Gd(NO3)3 was reconstituted with 5-10 µL of 0.1 M HNO3 and 12 mL of anhydrous isopropanol, and added to a custom electrodeposition cell [21,22]. The Gd(NO3)3 solution was plated onto a 2 m Ti backing (Hamilton Precision Metals, Lancaster, Pennsylvania, USA) by applying a bias of 400-700 V for 30-60 min.…”

“…The elemental composition of the targets was confirmed by energy-dispersive x-ray spectroscopy (EDS) as discussed in Ref. [21]. The isotopic composition of the targets was analyzed by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and the results are given in Table I.…”

“…Each sample was then reconstituted with 5 µL of 0.1 M HNO 3 and 12 mL of anhydrous isopropanol. This solution was then transferred to an electrodeposition cell [27], and the ruthenium nitrate was electrochemically deposited using the molecular plating technique [28,29] onto a 25-µmthick Al foil backing (99.99% pure Al from Goodfellow, USA). The deposition voltage ranged from 150 to 500 V while the current density was kept between 2 and 7 mA/cm 2 .…”
