Direct mass measurements on the superallowed emitter 74Rb and its daughter 74Kr: isospin-symmetry-breaking correction for standard-model tests.
The decay energy of the superallowed beta decay 74Rb(beta+)74Kr was determined by direct Penning trap mass measurements on both the mother and the daughter nuclide using the time-of-flight resonance technique and was found to be Q=10 416.8(4.5) keV. The exotic nuclide 74Rb, with a half-life of only 65 ms, is the shortest-lived nuclide on which a high-precision mass measurement in a Penning trap...
متن کاملHigh precision half - life measurement of the superallowed β - emitter 38 Ca
We have now analyzed the results obtained from our half-life measurement of Ca. In that measurement, we produced Ca via the H(K, 2n) reaction at a primary beam energy of 30A MeV. A 99%-pure Ca beam was obtained at the focal plane of the MARS spectrometer, from which it exited the vacuum system through a 50-μm thick Kapton window, passed through a 0.3-mm-thick BC404 scintillator and a stack of a...
متن کاملTG-60 dosimetry parameters calculation for the β-emitter 153Sm brachytherapy source using MCNP
Background: The formalism recommended by Task Group 60 (TG-60) of the American Association of Physicists in Medicine (AAPM) is applicable for β sources. Radioactive biocompatible and biodegradable 153Sm glass seed without encapsulation is a β- emitter with a short half life and delivers a high dose rate to the tumor in the millimeter range. In this work the dosimetry parameters of the ...
