Title: Isolation of ¹⁶³Ho from dysprosium target material by HPLC for neutrino mass measurements

Abstract

The rare earth isotope ¹⁶³Ho is of interest for neutrino mass measurements. This report describes the isolation of ¹⁶³Ho from a proton-irradiated dysprosium target and its purification. A Dy metal target was irradiated with 16 MeV protons for 10 h. After target dissolution, ¹⁶³Ho was separated from the bulk Dy via cation-exchange high performance liquid chromatography using 70 mmol dm^–3 α-hydroxyisobutyric acid as the mobile phase. Subsequent purification of the collected Ho fraction was performed to remove the α-hydroxyisobutyrate chelating agent and to concentrate the Ho in a low ionic strength aqueous matrix. The final solution was characterized by MC-ICP-MS to determine the ¹⁶³Ho/¹⁶⁵Ho ratio, ¹⁶³Ho and the residual Dy content. The HPLC purification process resulted in a decontamination factor 1.4E5 for Dy. As a result, the isolated Ho fraction contained 24.8 ±1.3 ng of ¹⁶³Ho corresponding to holmium recovery of 72 ± 3%.

Separation of carrier-free holmium-166 from neutron-irradiated dysprosium targets

Journal Article Dadachova, E ; Lambrecht, R M ; Hetherington, E L ; ... - Analytical Chemistry (Washington); (United States)

Holmium-166 ([sup 166]Ho, t[sub 1/2] = 26.4 h) is utilized in radiotherapeutic applications such as radioimmunospecific pharmaceuticals, bone marrow ablation, and radiation synovectomy. High specific activity [sup 166]Ho can be obtained from the decay of dysprosium-166 ([sup 166]Dy, t[sub 1/2] = 81.5 h). Dysprosium-166 is produced by the [sup 164]Dy[n,[gamma]][sup 165]Dy[n,[gamma]][sup 166]Dy reaction in a nuclear reactor. The applicability of reversed phase ion-exchange chromatographic methods was demonstrated for the separation of carrier-free [sup 166]Ho from milligram quantities of [sup 164]Dy[sub 2]O[sub 3] irradiated targets. An efficient and quantitative separation was achieved utilizing a metal-free HPLC system with Dowex AG 50WX12more »« less

PREPARATION OF LONG-LIVED HOLMIUM-163

Journal Article Naumann, R A ; Michel, M C ; Power, J L - J. Inorg. & Nuclear Chem.

A sample of Ho/sup 163/ was prepared by pile neutron irradiation of erbium oxide electromagnetically enriched onehundredfold in the mass-l62 isotope. The sample was exposed to 2 x 10/sup 21/n/cm/sup 2/ in the MTR. Mass analysis (prior to chemical separation) of the irradiated sample showed the presence of mass-163 and l65 isotopes, which were not observed prior to irradiation. On the basis of the mass analysis, approximately 5 to lO% of each of the Er/sup 162,164/ isotopes had undergone neutron capture. The sample was chemically fractionated by cation-exchange chromatography to yield pure fractions of the various rare earths. The holmiummore »« less

A High Separation Factor for 165Er from Ho for Targeted Radionuclide Therapy

Journal Article Da Silva, Isidro ; Johnson, Taylor R. ; Mixdorf, Jason C. ; ... - Molecules

Radionuclides emitting Auger electrons (AEs) with low (0.02–50 keV) energy, short (0.0007–40 µm) range, and high (1–10 keV/µm) linear energy transfer may have an important role in the targeted radionuclide therapy of metastatic and disseminated disease. Erbium-165 is a pure AE-emitting radionuclide that is chemically matched to clinical therapeutic radionuclide ¹⁷⁷Lu, making it a useful tool for fundamental studies on the biological effects of AEs. This work develops new biomedical cyclotron irradiation and radiochemical isolation methods to produce ¹⁶⁵Er suitable for targeted radionuclide therapeutic studies and characterizes a new such agent targeting prostate-specific membrane antigen.

BS>Radioactive Tb/sup 160 was prepared by slow neutron irradiation of chemically pure (99.99%) Tb/sub 2/O/sub 3/. Beta, conversion electron, and photoelectron spectra were studied on a double-focusing BETA spectrometer wlth halfwidth line 0.3 to 0.6%. Beta and conversion spectra of Tb/sup 160/ are shown. Tb/sup 160/ gamma rays at 880 and 963-966 kev (Th target) are also shown. Radioactive Ho/sup 160/ was prepared by irradiation of a tantalum target with 660- Mev protons, with chromatographic recovery of erbium and holmium fractions.

Identification of /sup 148/Ho and /sup 149/Ho

Journal Article Toth, K S ; Bingham, C R ; Zolnowski, D R ; ... - Phys. Rev., C; (United States)

The new nuclides, /sup 148/Ho and /sup 149/Ho, were identified in /sup 10/B bombardments of /sup 144/Sm. A gas-jet system was used to transport product nuclei to a shielded area suitable for ..gamma..-ray measurements. The 21-s isotope, /sup 149/Ho, was found to decay primarily to a /sup 149/Dy level at 1091 keV and less intensely to the i/sub 13/2/ 1073-keV state observed in a previous in-beam ..gamma..-ray study. This radioactivity, in analogy to neighboring odd-A terbium and holmium isotopes, probably represents the h/sub 11/2/ proton orbital in /sup 149/Ho which decays via an allowed ..beta.. transition to the 1091-keV level.more »« less
