“…Note, that at 400 ms after the proton pulse the beam gate was closed and radioactive sample was left free to decay. The fitted slope gives T 1/2 = 91.9(9) ms in very good agreement with the adopted half-life of 92(1) ms [16]. A similar analysis was performed on the five transitions at 455.6, 569.1, 683.3 (a doublet), 044306-3 725.2, and 1002.9 keV.…”

“…The γ rays were identified as belonging to the 65 Mn decay when their time spectrum was consistent with the decay half-life of 92 ms [16]. Finally the identification of a line from the decay of 65 Mn was made based on firm γ γ coincidences with the Mn lines already identified in the first two steps.…”

“…Prior to this study, there was scarce information on the β decay of 65 Mn and on the levels in 65 Fe. The half-life of the 65 Mn ground state has been measured as 92(1) ms [16]. A P n = 21.0(5)% for the β-n branch of 65 Mn was reported by Hannawald [17], who concluded that all the delayed neutron intensity directly feeds the ground state of 64 Fe.…”

“…We observe a transition at 1345.1 keV with a relative intensity of 1.3(1). This transition includes an impurity component from the decay of 65 Ga to 65 Ni with an energy of 1343.9 keV and an intensity of 0.18(2) (determined using other known lines in the decay of 65 Ga and the branching ratios listed in [16]). The resulting relative intensity of the 1345.8-keV transition in 64 Ni is 1.1(1), which gives a relative intensity of 14.6(21) for the β-n branch.…”

The low-energy structure of 65 Fe has been studied by means of γ and fast-timing spectroscopy at the ISOLDE facility, CERN. A level scheme of 65 Fe populated following the β − decay of 65 Mn was established for the first time. It includes 41 levels and 85 transitions. The excitation energy of the β-decaying isomer in 65 Fe has been precisely determined at 393.7(2) keV. The β-delayed neutron emission branch was measured as P n = 7.9(12)%, which cannot be reconciled with the previously reported value of 21.0(5)%. Four γ rays and four excited states in 64 Fe were identified as being populated following the β-n decay. Four lifetimes and five lifetime limits in the subnanosecond range have been measured using the advanced time-delayed βγ γ (t) method. The level scheme is compared with shell-model calculations. Tentative spin and parity assignments are proposed based on the observed transition rates, the calculations, and the systematics of the region.

Purpose A method for calculating nuclear medicine ionization chamber (NMIC) calibration settings with a Monte Carlo model is presented and validated against physical measurements. This work provides Monte Carlo–calculated calibration settings for select isotopes with no current manufacturer recommendations and a method by which NMIC manufacturers or standards laboratories can utilize highly detailed specifications to calculate comprehensive lists of calibration settings for general isotopes. Methods A Monte Carlo model of a Capintec PET series NMIC was developed and used to calculate the chamber response to relevant radioactive decay products over an energy range relevant to nuclear medicine. The photon detection efficiency (PDE) of a high purity germanium (HPGe) detector was modeled and physically validated to facilitate measurements of NMIC calibration settings with HPGe detector spectroscopy. Modeled NMIC response to various isotopes was compared against spectroscopic measurements and National Institute of Standards and Technology (NIST)‐validated calibration settings to validate the Monte Carlo–calculated NMIC calibration settings. Results HPGe detector PDE was validated against the physical measurements to within 3.3%$3.3\%$ at 95%$95\%$ confidence and used to measure calibration settings, which produced activity readings 0.7%$0.7\%$, 1.6%$1.6\%$, 0.8%$0.8\%$, and 1.0%$1.0\%$ different than those validated by NIST for 11$^{11}$C, 18$^{18}$F, 68$^{68}$Ga, and 64$^{64}$Cu respectively. The Monte Carlo model of the NMIC reproduced measured calibration settings to within 7%$7\%$ at 95%$95\%$ confidence for isotopes with a sufficiently small yield of low energy photons. Conclusions A method of calculating NMIC calibration settings with Monte Carlo modeling has been developed and validated against HPGe detector spectroscopy. NMIC manufacturers or standards laboratories can use more detailed specifications of the chamber geometries to extend the applicability of this method to a wider range of isotopes.
