An extensive program to study the production, decay properties, and nuclear structure of very neutron-deficient polonium and radium nuclei is underway at the Department of Physics, University of Jyvaskyla, Finland (JYFL). The main tools used in these studies are the gas-filled recoil separator RITU and various germanium gamma-ray arrays. In the course of these studies, among others the following new isotopes have been produced: Ra-204, Ra-203, and Ra-202. Isomeric alpha decaying states have been discovered in Ra-203 and Po-191. Fine structure in the decay of Po-192 to the oblate and prolate band heads in Pb-188 has been observed. In-beam gamma-ray spectra have been, for the first time, measured for Po-192, Ra-206, Ra-208, and Ra-210. Development of collectivity in nuclei in the Po-Ra region and the systematics of reduced alpha widths will be discussed.

In-beam spectroscopic studies of shape coexistence and collectivity in the neutron-deficient Z ≈ 82 nuclei

Julin, Rauno; Grahn, Tuomas; Pakarinen, Janne; Rahkila, Panu (Institute of Physics Publishing Ltd.; Institute of Physics, 2016)

In the present paper we focus on studies of shape coexistence in even-mass nuclei in the neutron-deficient Pb region. They are based on experiments carried out using tagging techniques in the Accelerator Laboratory of the ...

Van; Van Duppen, P.; Vermeulen, M.; Voulot, D.; Warr, N.; Wenander, F.; Wimmer, K.; Zielińska, M. (American Physical Society, 2015)

Coulomb-excitation experiments are performed with postaccelerated beams of neutron-deficient 196,198,200,202Po isotopes at the REX-ISOLDE facility. A set of matrix elements, coupling the low-lying states in these isotopes, is ...
Direct mass measurements on neutron-deficient xenon isotopes with the ISOLTRAP mass spectrometer
