Аннотация:For the first time an attempt has been made to detect a new type of fundamental interaction, viz., the nomagnetic spin interaction (the "arion" long-range interaction of A. A. Ansel'm and N. G. Uraltsev, Phys. Lett. 114B, 39 (1982), Phys. Lett. 116B, 161 (1982), and A. A. Ansel'm, JETP Lett. 36,55 (1982). The arion long-range interaction is similar to the weak magnetic spin interaction, but differs from the latter in particular in that its existence is due only to oriented spins but not to moving electric charges. Within the sensitivity of the experiment the result is negative, which places a restriction on the parameters of the hypothetical arion field. It is established that the arion interaction between nuclear and electron spins is no stronger than 10E-10 - 10E-11 of their magnetic interaction.
