Abstract
Two-proton decay of the low-lying states populated in the transfer reaction is studied. The two-proton width of the first excited state at MeV is of importance for the two-proton radioactivity theory and nuclear-astrophysics applications. A dedicated search for the two-proton emission of this state was performed leading to the new upper limit obtained for the width ratio . An original, “combined mass” method is suggested and tested as capable of improving the resolution of the experiment, which is a prime significance for the study of nuclear states with extremely small particle-to-gamma width ratios . The condition is quite common for the states of astrophysical interest, which makes the proposed approach promising in this field.
