The asymmetry coefficient in pi /sup +/ - mu /sup +/ - e/sup +/ decay was measured in an ordinary and diluted NIKFI-R emulsion as well as in this emulsion placed in a strong magnetic field. An analysis of the results obtained and also of those contained in the literature indicates that the asymmetry coefficient in the NIKFI-R emulsion (a = -0.077 plus or minus 0.012) is significantly smaller than that for the llford G-5 emulsion (a = --0.139 plus or minus 0.014). A two-fold dilution of the NIKFI-R emulsion with gelatin leads to a sharp increase of the asymmetry coefficient (a = --0.127 plus or minus 0.028). The polarization in the NIKFI-R emulsion is restored by application of a magnetic field, the asymmetry coefficient being increased up to a = --0.28 plus or minus 0.02 at a field strength of 17,000 G.
