Decay Studies of ¹⁹⁷Tl (2.84 H) and ^197mHg (23.8 H)

Abstract

From the v-ray spectra of the decays of (2.84 H), »'"""Hg (23.8 H) and '"Hg (64.14 H) obtained as products of the 50 MeV OL particle interaction with "''Au, the absolute y-rsLy intensities of the transitions from the low-lying negative parity states of "^Hg and the relative intensity of the transition from it's 13/2'^ isomeric State, have been measured. The multipolarity of the weak 18.18 keV transition was seen to be very likely an Ml. The IT and EC branching fractions, the log(ft)E and the total conversion electron coefficient of the decays from the 13/2^ isomeric State were also determined. The results were compared with existing data and discussed in terms of the Moskowski-Weisskopf estimates and theoretical calculations of the internal conversion coefficient.

Molecular imaging using the theranostic agent 197(m)Hg: phantom measurements and Monte Carlo simulations

“…Therapeutic applications of 197m Hg and 197 Hg are conceivable because of their suitable emission spectra [ 8 ]. The radial dose distribution is comparable to the dose distribution from 177 Lu [ 7 ], a therapeutic radionuclide that is routinely used in nuclear medicine [ 9 ].…”
