“…With the increasing incident neutron energy the ratio increases, showing that at higher excitation energies the formation of the high-spin isomer is more favored. This trend is similar to that for several other neutron-and charged-particle-induced reactions near their thresholds [16,17,[39][40][41][42][43][44]. The increase seems to be more pronounced for 195 Hg m,g than for 197 Hg m,g .…”

“…Worth noting is that not only isomeric pairs with small differences in spins can be described by the model calculations (cf., for example, Refs. [17,[39][40][41][42][43][44]) but also the pairs with relatively large spin differences (as in this work), provided the input parameters are properly chosen. In this regard, two factors need special consideration: first, the input level scheme up to the continuum, and second, the spin distribution of the level density (η).…”

3 He reaction using a deuterium gas target at the Jülich variable energy compact cyclotron CV 28. Use was made of the activation technique in combination with high-resolution, high-purity Ge detector γ -ray spectroscopy. All the data were measured for the first time over the investigated energy range. The transition from the present low-energy data to the literature data around 14 MeV is generally good. Nuclear model calculations using the codes STAPRE and EMPIRE-2.19, which employ the statistical and precompound model formalisms, were undertaken to describe the formation of both the isomeric and ground states of the products. The total reaction cross section of a particular channel is reproduced fairly well by the model calculations, with STAPRE giving slightly better results. Regarding the isomeric cross sections, the agreement between the experiment and theory is only in approximate terms. A description of the isomeric cross-section ratio by the model was possible only with a very low value of η, i.e., the eff / rig ratio.

“…However, there are already notable contributions to deuteron-induced reaction studies (e.g., Refs. [2][3][4][5][6]) that have taken into account only the statistical emission and eventually a "reduction factor" of the compound nucleus cross section due to "direct processes." Moreover, this reduction factor does not allow the distinction between processes such as the breakup and the stripping mechanisms that affect the different energy ranges of particles emitted through the decay of excited composite nuclei.…”

Experimental elastic-scattering angular distributions for deuteron interaction with 63 Cu and 93 Nb targets are compared with calculations performed within the continuum-discretized coupled-channels (CDCC) method, in which coupling to breakup channels is explicitly taken into account. The calculated elastic breakup cross sections are compared with the predictions of an empirical parametrization for a wide range of deuteron incident energies. The good agreement between the calculations and the systematics at the energies where data are available indicates that the CDCC method permits a useful assessment of empirical parametrizations and provides useful guidance for the extrapolation of these parametrizations beyond the energies formerly considered.

“…Production yields of 58m Co and 58g Co from 57 Fe(d,n) were quantified via two methods: 1) indirectly via quantification of 58g Co activity over time (E γ = 811 keV) using an efficiency-calibrated HPGe detector, fitting the data points with the Bateman equation that contains the initial activities of the parent and daugher radionuclides, as it was done by Thisgaard et al [12]; and 2) via direct quantification of 58m Co (E γ = 24.9 keV) using an efficiencycalibrated low-energy HPGe detector as it was done by Sudár and Qaim [22]. The sample employed for this purpose was the 10 µL aliquot drawn from the 3.1 mL target dissolution.…”

Abstract. Co-58m (t 1/2 =9.10 h, 100% IC) is an attractive radionuclide for localized delivery of radiation dose due to its emission of Auger and conversion electrons with high LET in water (2-18 keV/µm). 58mCo decays to a positron-emitting daughter, 58g Co (t 1/2 =70.86 d, 14.9% β + ), which can be readily detected by Positron Emission Tomography (PET) and hence can be employed to verify the biodistribution of the parent isotope post-treatment in vivo. In this work, we describe 1) the targetry and radiochemistry involved in the production of high specific activity 58m Co; and 2) the results of a pilot radiotherapy study using a Co with a separation efficiency of 96±2% and a specific activity with NOTA of 25±6 GBq/µmol. We have produced ~640 MBq of 58m Co-NOTA-TRC105, with a specific activity of 1.2 MBq/µg, in 800 µL of PBS ready for targeted radioimmunotherapy, which we employed in a group of 4 mice. Post-therapy biodistribution was quantified in vivo via PET imaging of the daughter 58g Co.
