Abstract

The structure of the nuclei 71As and 73As has been investigated by studying the decay of 71Se, 73gSe and 73mSe, the 72Ge(p, 2nγ)71As reaction, the 73Ge(p, nγ)73As reaction and the 72Ge(3He, d) 73As reaction. Level schemes of 71As and 73As are constructed on basis of the energies and intensities of the gamma transitions and their coincidence relations. Spins and parities are deduced from log ft values, l-values and the decay properties of the excited states. The measured half-life of the lowest excited state in 71As is T12 = 59 ± 10 ns. The experimental level-schemes are compared with the predictions of the cluster-vibrational coupling model.
