Anomalously fast relaxation of metastable states of Ca+, Eu, and Eu+ and impact emission from Ca+, Eu+, and Sr+ ions
Bokhan P. A.
An anomalously fast relaxation of metastable states of the Eu atom and of the Ca+ and Eu+ ions has been discovered in collisions with He and Ne atoms. An anomalously fast relaxation of metastable states of Ba+, Ca+, Eu+, and Sr+ has also been discovered in a quasiresonant charge exchange with the like atoms.
