Abstract
The interest in the β-decay properties of nuclides far (and not so far) from stability has increased in recent years. Since the calculation of the half-lives of neutron-rich nuclei published in [1], about 70 new isotopes have been discovered, and this number will increase rapidly with new experimental possibilities (see, e.g.[2–5]). The theoretical predictions [1] thus can be tested now on a rather large number of nuclei unknown at the time of the calculations. Fig. 1 compares the half-lives of the latter nuclides with the predictions of [1]. The theoretical values are found reliable within the expected limits. This is of importance in particular for the astrophysical conclusions on element synthesis, age of galaxy and more recently the value of the cosmological constant and the corresponding energy density of the vacuum [6–8]. The new data allow on the other hand to improve the calculations.
