Findings

Mass and decay spectra are explicitly calculated.

Critical temperatures are identified and their physical meaning discussed.

Insights into string radiation decay mechanisms are provided.

Abstract

Mass and decay spectra are calculated for quantum massive excitations of a piecewise uniform bosonic string. The physical meaning of the critical temperatures characterizing the radiation in the decay of a massive microstate in string theory is discussed.
