Microscopic investigation of one- and two-proton decay from the excited states of 10C

TL;DR

This paper uses microscopic cluster models and R-matrix calculations to analyze one- and two-proton decay processes in excited states of 10C, confirming experimental data and the di-proton decay approximation.

Contribution

It provides a detailed microscopic analysis of 1p and 2p decays in 10C, validating the di-proton approximation and explaining decay suppression mechanisms.

Findings

Decay widths agree with experimental data

Supports di-proton decay approximation

Shows decay suppression due to structural mismatch

Abstract

We present microscopic cluster model calculations for the 1p and 2p decays of the 0+2 and 2+2 states of 10C. With the R-matrix method, we have estimated the decay widths. The obtained 1p and 2p decay widths are in good agreement with the recent experimental data and support the validity of the di-proton approximation for the 2p decay of 10C(0+2). We also show the suppression of the 1p decay of the 10C(0+2) state due to the structure mismatch with the decay channel.
