Description

New neutron-rich isotopes of several rare-eath elements have been identified using the /sup 252/Cf-based ISOL facility at the INEL. New isotopes observed to date, with values of their half-lives in parentheses, are /sup 153/Pr (4.28 +- 0.11 s), /sup 155/Nd (8.9 +- 0.2 s), /sup 156/Nd (5.47 +- 0.11 s), /sup 157/Pm (10.50 +- 0.12 s), /sup 158/Pm (4.8 +- 0.5 s), /sup 162/Eu (10.6 +- 1.0 s) and /sup 164/Gd (45 +- 3 s). Also, new half-life values have been measured for /sup 151/Pr (18.90 +- 0.07 s), /sup 152/Pr (3.7 +- 0.2 s), /sup 153/Nd (28.9 +- 0.4 s), /sup 154/Nd (25.9 +- 0.2 s), /sup 153/Pm (315 +- 1 s), /sup 155/Pm (41.5 +- 0.2 s), /sup 156/Pm (26.70 +- 0.10 s), /sup 157/Sm (483 +- 2 s), /sup 158/SM (318 +- 2 s), /sup 159/Sm (11.37 +- 0.15 s), /sup 160/Sm (9.6 +- 0.3 s) and /sup 161/Eu (24 +- 4 s). The half-life values are compared to the results of theoretical predictions
