It has been possible, using GAMMASPHERE plus Microball,to extract differential lifetime measurements free from common systematic errors for over 15 different nuclei (various isotopes of Ce, Pr, Nd, Pm, and Sm) at high spin within a single experiment.

Publikováno v: Physical Review Letters; 86, pp 1450-1453 (2001)
Two excited well-deformed bands have been observed in the semi-magic nucleus Ni-58. One of the bands was observed to partially decay by emission of a prompt discrete alpha particle that feeds the 2949 keV 6(+) spherical yrast state in the daughter nu

The main objective of this contribution is to present a number of methodological problems arising in the collection and interpretation of data from (large) corpora. In particular, we want to show how large corpora can be used to test hypotheses conce
