Measurements of EC and Weak α Decays of Neutron-deficient Transuranium Isotopes

Measurements of EC and weak α decays of neutron-deficient americium and curium isotopes have been performed using a gas-jet coupled on-line isotope separator. Decay schemes of 235, 236 Am have been established for the first time, and proton-neutron configurations in 235, 236 Am and their EC-decay da...

Description
Summary:Measurements of EC and weak α decays of neutron-deficient americium and curium isotopes have been performed using a gas-jet coupled on-line isotope separator. Decay schemes of 235, 236 Am have been established for the first time, and proton-neutron configurations in 235, 236 Am and their EC-decay daughters 235, 236 Pu have been evaluated. Q α values were derived from measured α-particle energies for 235, 236 Am and 238 Cm as well as for the new isotopes 233 Am and 237 Cm.
