A.F. Lisetskiy, E. Caurier, K. Langanke, G. Martinez-Pinedo, P. von Neumann-Cosel, F. Nowacki, A. Richter

The M1 strength distributions in the 36,38Ar isotopes calculated in configurational space of two major N=2 and N=3 harmonic oscillator shells are discussed. It is shown that considerable breaking of 40Ca core is required to reproduce total M1 sum rule and fragmentation of the M1 strength for 38 Ar.
