dc.description.abstract | Several states of proton-unbound isotopes
30
Ar
and
29
Cl
were investigated by measuring their in-flight decay products,
28
S
+ proton + proton and
28
S
+ proton, respectively. A refined analysis of
28
S
-proton angular correlations indicates that the ground state of
30
Ar
is located at
2
.
45
+
0.05
−
0.10
MeV above the two-proton emission threshold. The investigation of the decay mechanism of the
30
Ar
ground state demonstrates that it has the transition dynamics. In the “transitional” region, the correlation patterns of the decay products present a surprisingly strong sensitivity to the two-proton decay energy of the
30
Ar
ground state and the one-proton decay energy as well as the one-proton decay width of the
29
Cl
ground state. The comparison of the experimental
28
S
-proton angular correlations with those resulting from Monte Carlo simulations of the detector response illustrates that other observed
30
Ar
excited states decay by sequential emission of protons via intermediate resonances in
29
Cl
. Based on the findings, the decay schemes of the observed states in
30
Ar
and
29
Cl
were constructed. For calibration purposes and for checking the performance of the experimental setup, decays of the previously known states of a two-proton emitter
19
Mg
were remeasured. Evidences for one new excited state in
19
Mg
and two unknown states in
18
Na
were found. | es |
