Abstract:  The main chemical form of the stabilization of 147Pm arisen by the ß-decay of 147Nd in tris(cyclopentadienyl)neodymium was determined. The accumulation of daughter products took place in the crystals of parent compound and their separation was carried out by sublimation method. Under the conditions employed the main chemical form of the stabilization of 147Pm is (С5Н5)3Pm which is formed in the yield of 91.3 ± 3.5%. The remainder consists of some chemical forms which are not volatile at 180°C and 10-4 torr and have not been exactly defined as yet.
