Abstract

Two new neutron-deficient isotopes,213Pa and214Pa were produced in complete fusion reactions of51V-ions with170Er targets at (5.2−5.6) AMeV. The assignment was based on delayed evaporation residue -α -α time and position coincidences. Theα- decay energies of213,214Pa were measured to be Eα=(8236±20) keV and Eα=(8116±20) keV, respectively. The half-lives of213,214Pa were determined to be T1/2=(5.3 +4.0−1.6 ms and T1/2=(17 ±3) ms, respectively.
