Abstract

For the first time masses of recoiling daughter ions have been measured that were held after beta-decay in a buffer-gas-filled Penning trap. From the masses of the trapped beta-decaying manganese ions ^61-63Mn⁺ and the daughter recoil-ions ^61-63Fe⁺ the Q values of ^61-63Mn have been deduced with absolute uncertainties of about 5keV. The observed yields of iron ions are compared to the results from simulations, which confirm a recoil-ion trapping efficiency of about 50%.
