The effects of weak particle-hole admixtures on magnetic multipole properties of Cl38 and K40 are investigated and the results are compared with experiment, with particular emphasis on M1 transitions between members of the lower quartet of states in each nucleus. In K40, the admixtures tend to decrease the differences between theoretical and experimental values except for the magnetic moment. However, the same procedure leads to larger discrepancies with experiment in Cl38. In addition, in the latter nucleus the abnormally large M1 transition strength from the second 3- level to the first 4- state cannot be understood if only weak-configuration mixing is assumed. On the other hand, one can account for the experimentally observed strongly inhibited M3 transition between the 5- and 2- states of Cl38. Our prime interest is in exhibiting the effects of the separate particle-hole admixtures in order to isolate the source of the discrepancies.
