%X Several states of proton-unbound isotopes <sup>30</sup>Ar and <sup>29</sup>Cl were investigated by measuring their in-flight decay products, <sup>28</sup>S+proton+proton and <sup>28</sup>S+proton, respectively. A refined analysis of <sup>28</sup>S-proton angular correlations indicates that the ground state of <sup>30</sup>Ar is located at 2.45<sup>+0.05</sup><sub>−0.10</sub> MeV above the two-proton emission threshold. The theoretical investigation of the <sup>30</sup>Ar ground state decay demonstrates that its mechanism has the transition dynamics with a surprisingly strong sensitivity of the correlation patterns of the decay products to the two-proton decay energy of the <sup>30</sup>Ar ground state and the one-proton decay energy as well as the one-proton decay width of the <sup>29</sup>Cl ground state. The comparison of the experimental <sup>28</sup>S-proton angular correlations with those resulting from Monte Carlo simulations of the detector response illustrates that other observed <sup>30</sup>Ar excited states decay by sequential emission of protons via intermediate resonances in <sup>29</sup>Cl. Based on the findings, the decay schemes of the observed states in <sup>30</sup>Ar and <sup>29</sup>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 <sup>19</sup>Mg were remeasured. Evidences for one new excited state in <sup>19</sup>Mg and two unknown states in <sup>18</sup>Na were found.
