Abstract

Conversion-electron measurements following the

{}^{144}{(α}

,2n) and

{}^{144}{He}

,n) reactions reveal high-energy E0 transitions at 3020, 3485, and 3639 keV. The lowest of these deexcites the known two-neutron pairing vibrational state in

{}^{146}{Gd}

. It is not clear whether either of the others can be associated with the

0^{+}

member of the

3^{-}

3^{-}

two-phonon octupole multiplet.
