Study on the Curium I Even-Parity Energy Levels Using PLS-BPN

An improved pattern recognition technique, partial least square-back propagation network （PLS-BPN）, has been used to reassign the even-parity energy levels of the atom Cm I . The results show that （1） most previous assignments are further confirmed; （2） the electronic configurations of some energy levels which were differently assigned by KNN and CPN methods are determined here; （3）an energy level whose electronic configuration has been assigned experimentally seems to be questionable.
