Copper exposure of freshwater mussels (Anodonta anatina): Some physiological effects
… raising Cu-loaded algae using the stable isotope 63Cu as marker for feeding of mussels without affecting the nutritional value of the algal food. In these latter experiments, mussels are exposed to 63Cu via water or via food to investigate the relative importance of Cu uptake to its distribution …

An Investigation of Ni and Cu Isotopic Fractionation in Basal Duluth Complex Cu-Ni-PGE Mineralization, Northeastern Minnesota
… work has indicated a fractionation of 65Cu and 63Cu, with pronounced differences between primary copper sulfides and secondary copper phases in a variety of deposit types. Prior to this study, no δ60/58Ni or δ65/63Cu values have been measured in Duluth Complex rocks. The primary goal of this …

Nuclear magnetic resonance studies of YBa2̳Cu3̳07̳ in the superconducting state
In this thesis we report measurements of the 63Cu Knight shift in the · superconducting state for the plane (Cu(2)) and Chain (Cu(l)) sites in YBa2Cu307. We also have measured the temperature and field dependent 63Cu(2) nuclear spin relaxation rates (63Wla) in the superconducting state. The …

Measurement of nuclear transparency from A(e,e'[pi]⁺) reactions
… electroproduction cross section from 1H, 2H,12C, 63Cu and 197Au targets from Q2 = 1.1 to 4.8 (GeV/c)2 was measured in Jefferson Laboratory Experiment E01-107. The nuclear transparency was formed by the ratio of ([sigma]A/[sigma]H) from the data and ([sigma]A/[sigma]H) from a model of …

Inductively coupled plasma mass spectrometry with a twin quadrupole instrument using laser ablation sample introduction and monodisperse dried microparticulate injection
… Using a copper sample, the isotope ratio 63Cu+/65Cu+ is measured with a relative standard deviation (RSD) of 0.26%. Transient signals for single laser pulses are also obtained. Copper isotope ratio measurements for several laser pulses are measured with an RSD of 0.85%;Laser ablation (LA) …

A new prompt gamma spectroscopy-based approach for range verification in proton therapy
… for 31P (1.14, 1.26, 1.78 and 2.23 MeV) and 63Cu (0.96, 1.17, 1.24, 1.326 MeV), while only one for 89Y (1.06 MeV). We compared all experiments with TOPAS MC. It is one of the leading toolkits for simulating particle interaction in the matter for medical physics applications. The comparison …

Use of Positron Emission to mography For Proton Therapy Verification
<p>Positron emission tomography (PET), a tool commonly used for cancer staging and response monitoring, has recently been used for proton therapy verification. By imaging tissue activation following proton treatment, attempts have been made to verify proton <em>dose</em> and <em>range</em>. In this …
