【摘要】 <正>Our previous experimental method and results for the（EC+β⁺）decay of¹⁵⁷Yb, ¹⁵³Er,¹³⁰Ce and ¹²⁸Ce as well as for the beta-delayed proton decay of¹²¹Ce,¹²⁵Nd,¹²⁸Pm, ¹²⁹Sm,¹³⁵Gd,¹³⁷Gd,¹³⁹Dy,¹⁴²Ho and ¹⁴⁹Yb.The observed low-lying states in their dauther nuclei and the production cross section of the beta-delayed proton precursors have been reviewed in a systematic way and compared with different model calcalations. Finally,three questions have been put forward for further study and discussion.更多还原
