[en] It is more and more difficult to synthesis and study new nuclei along the proton drip-line by using on-line isotope separator because of its low efficiency. A specific method of 'p-γ' coincidence measurement, using the known low-lying '2+→0+ (ground state)' γ transition of the 'daughter' nucleus in coincidence with its β-delayed proton, could increase the detection sensitivity effectively and was used to identify and study the precursors, new nuclei 135Gd and 121Ce with a He-jet recoil fast tape transport system at HIRFL in China. It is prospected to synthesis and study more nuclei along the proton drip-line of Z =3D 0.743 N + 11.6 in the rare-earth region by this technique

[en] Male Wistar rats, 1.5 month-old, were used in the experiment. The medicinal Na131 I with different radioactivities was injected intraperitoneally. After 1, 1.5 and 2 years, the levels of T3, T4 and r-TSH in the serum were determined with RIA. The results showed that the levels of T3 and T4 in the rats with thyroid absorbed dose of 7.8 and 39 Gy were slightly higher than those in the controls, while the levels of T3 and T4 in the rats with thyroid dose of 82 and 164 Gy were significantly lower than those in the controls. The level of r-TSH was elevated with increasing doses, thereby denotint that 131I can iduce primary hypothyroidism in rats. The relationship between above results and histological changes in the thyroid was studied. Some correlations between the reduction of T4 and the increase of r-TSH, and pathological changes were found

[en] New β-delayed proton precursor 121Ce has been produced by the reaction 92Mo(32S, 3n) and studied by using γ(X)-p coincidence with a He-jet recoil fast tape transport system. The half-life of 121Ce was determined to be (1.1 +- 0.1)s. Its β-delayed proton spectrum has been observed and the β-delayed proton branching ratio for 121Ce was estimated to be (1.0 +- 0.5)%
