Electric quadrupole moments and transition probabilities of light nuclei in the orthogonal scheme multiquantum approximation

Calculations of electric quadrupole moments and transition probabilities in the orthogonal scheme multiquantum approximation are discussed. The simple algorithm for calculation in bases marked by symmetric irreducible representations of group O(A-1) and quantum numbers K and E = K + 2N, N 0.1,...,9 is given. The calculations for 84Be are presented. It is shown that extension of basis increases electric quadrupole moments on 15-45%, and transition probabilities in 1.6-2.8 times. The account of multiquantum states increases the results still by 10-30%. The results of calculations are compared with similar calculations in the unitary scheme approximation
