Fine Structure in the $\beta$-Delayed Proton Decay of $^{33}$Ar

Low energy beta-delayed protons from $^{33}$Ar 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 $^{32}$S. The observation is discussed in terms of the standard shell model. A na...

Sumario:Low energy beta-delayed protons from $^{33}$Ar 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 $^{32}$S. The observation is discussed in terms of the standard shell model. A natural explanation is provided by the large spectroscopic amplitudes, involving $s_{1/2}$ and $d_{3/2}$ orbitals, as well as the $l$=0 barrier penetrability, favouring the decay to the 2$^+$ state.
