The complex Excited Vampir approach was applied to the description of the recently identified magnetic cascade of negative-parity states in the odd-odd 82Rb nucleus. Strong M1, ΔI = 1 transitions as well as rather weak crossover B(E2) strengths are obtained in agreement with the available data. The decrease of the B(M1) strengths with increasing spin is revealed by the calculations. A strong mixing of differently deformed states at the highest calculated spins is responsible for the trend of the B(M1;ΔI = 1) and B(E2;ΔI = 2) strengths.
