Description

Low-energy beta-delayed protons from 33Ar have been measured for the first time. The data reveal states, which, despite unfavourable barrier penetrability values, strongly decay to the first excited 2+ state in 32S. The observation is discussed in terms of the standard shell model. A natural explanation is provided by the large spectroscopic amplitudes, involving s1/2 and d3/2 orbitals, as well as the l=0 barrier penetrability, favouring the decay to the 2+ state. (orig.)
