The most stable of niobium's isomers is 93m Nb with a half-life of 16.13 years. The least stable isomer is 84m Nb with a half-life of 103 ns. All of niobium's isomers decay by isomeric transition or beta decay except 92m1 Nb, which has a minor electron capture decay chain.
Sunflower (photo by Yves Couder) Why is it that the number of petals in a flower is often one of the following numbers: 3, 5, 8, 13, 21, 34 or 55? For example, the lily has three petals, buttercups have five of them, the chicory has 21 of them, the daisy has often 34 or 55 petals, etc. Furthermore, when one observes the heads of sunflowers, one notices two series of curves, one winding in one sense and one in another; the number of spirals not being the same in each sense.
