Description
Two-body orbital electron-capture (EC) decay of stored and cooled highly charged ions has been studied in the Experimental Storage Ring (ESR) at GSI Helmholtzzentrum in Darmstadt, Germany. The H-like 142Pm60+ ions were produced by fragmentation of 600 AMeV 152Sm ions in a Be-target. The 142Pm60+ fragments were separated in-flight by the FRagment Seperator (FRS), injected into the ESR storage ring at 400 MeV/u and cooled to high phase-space density by stochastic and electron cooling. More than 10 000 EC decays have been recorded in a recent experiment at October 2014 by means of a 245 MHz resonator serving as a Schottky detector. This device revealed the true EC-decay time of single stored ions within 32 ms as identified by a tiny change of their revolution frequency. Moreover, owing to the high sensitivity and performance of this resonator also the velocity and momentum of the recoiling daughter nucleus immediately after the decay could be determined. The data analysis of indepented groups is still in progress. This study presents the results obtained from the recent experiment of orbital electron capture decay of 142Pm60+ ions at the ESR.
