Abstract

Excitation functions of the [Formula Presented] and [Formula Presented] reactions were measured over the neutron energy range of 6.2 to 14.7 MeV, using the activation technique in combination with off-line γ-ray spectrometry. Neutrons in the energy range of 6 to 12.4 MeV were produced using the [Formula Presented] reaction on a [Formula Presented] gas target and in the region of 14 MeV at a [Formula Presented] generator. The half-life of [Formula Presented] was redetermined and found to be [Formula Presented] i.e., slightly shorter than the literature value of 16.09 s. Statistical model calculations taking into account precompound effects were performed for the strong [Formula Presented] channel as well as for the weak [Formula Presented] process. The experimental data for both the reactions are well described by the calculation over the whole investigated energy range. For the [Formula Presented] process, the isomeric cross section ratio [Formula Presented] was deduced. A comparison with the results of nuclear model calculations showed good agreement.
