Abstract
The cross section for the reaction has been measured in the interval MeV by comparing the activity with activity produced in the () reaction in the same bombardment. The cross section varies about a value of approximately 5 μb and shows several maxima in the region of bombardment. The results are interpreted in terms of compound-nucleus formation; in particular, for the assumed resonance at MeV, it is found that eV. There is no evidence for direct capture, but some contribution from this process cannot be excluded. The half-life of was redetermined in the course of the work and found to be 2.49±0.07 sec, a value about 10% higher than that currently accepted.
