Alpha-decay characteristics of neutron-deficient 190Po, 189Bi and 186Pb isotopes

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

The neutron-deficient 190Po and 189Bi isotopes have been produced in the 2n respectively p2n channels of the 48Ti +144 Sm reaction. Cross sections for different reaction channels are given. For 190Po, improved values of α-energy Eα = 7550(15) keV and half-life T1/2 = 1.9 +0.6−0.4 ms were measured. By using correlated α-decay chains an α-branching ratio of 0.50(25) was deduced for 186Pb. The reduced α-width systematic is extended for both of these isotopes, confirming a persistence of the saturation towards the lighter Po isotopes and the absence of any anomalies for the neutron-deficient Pb isotopes. For 189Bi improved values of Eα = 7300(15) keV and T1/2 = 4.8(5) ms were measured.
