Megjegyzések:	The beta-delayed neutron-emission probabilities of 28 exotic neutron-rich isotopes of Pm, Sm, Eu, and Gd were measured for the first time at RIKEN Nishina Center using the Advanced Implantation Detector Array (AIDA) and the BRIKEN neutron detector array. The existing beta-decay half-life (T (1/2)) database was significantly increased toward more neutron-rich isotopes, and uncertainties for previously measured values were decreased. The new data not only constrain the theoretical predictions of half-lives and beta-delayed neutron-emission probabilities, but also allow for probing the mechanisms of formation of the high-mass wing of the rare-earth peak located at A approximate to 160 in the r-process abundance distribution through astrophysical reaction network calculations. An uncertainty quantification of the calculated abundance patterns with the new data shows a reduction of the uncertainty in the rare-earth peak region. The newly introduced variance-based sensitivity analysis method offers valuable insight into the influence of important nuclear physics inputs on the calculated abundance patterns. The analysis has identified the half-lives of Sm-168 and of several gadolinium isotopes as some of the key variables among the current experimental data to understand the remaining abundance uncertainty at A = 167-172.

Megjegyzések:	Neutron-rich lanthanides were produced via in-flight fission of a U-238 primary beam at the RIBF, RIKEN Nishina Center to measure half-lives (T-1/2) and beta-delayed neutron emission probabilities (P-n) in order to constrain r-process abundance calculations. Pm159-166, Sm161-168, Eu165-170, and Gd167-172 ions were implanted in the Advanced Implantation Detector Array (AIDA), and beta-delayed neutrons and gamma-rays were detected by the surrounding detector array (BRIKEN). For the validation of T-1/2 values derived from implantation-beta (i-beta) time correlations, gamma-spectroscopic methods were used as well. The experimental results of the beta-delayed gamma-spectroscopy of Pm-162 are presented here as an example. A half-life value from gamma-decay curves was derived with a comparable uncertainty to the result from the i-beta method, and a mean value well within the 1 sigma range.
