Level scheme of 242Am

Published level scheme of 242Am includes 39 levels, places 118 transitions out of 246 transitions measured, and has normalized χ2 = 6.6, with the individual contribution to the total χ2 of each of the 16 transitions with the worst energy placement being > 9. Using the program of construction of the level scheme with the aid of Ritz combinations enabled us to add 35 new levels, place 201 transitions, and construct the final level scheme with χ2 = 1.3. No transition energy error in the final scheme differs from the error of the energy difference of levels between which this transition is placed by more than a factor of 3.
