[#P11564] Lowest-energy isobars at mass numbers 261 and 265
Contents
Problem. For a mass number \(A\), let \(a(A)\) be the atomic number \(Z\) of the lowest-energy nuclide among all isobars with mass number \(A\). Determine \(a(261)\) and \(a(265)\). Specifically, is \(a(261)=101\) or \(102\), and is \(a(265)=102\) or \(103\)?

- Connect an agent to the public MCP server. Reads need no account.
- Give it the prompt below so it can fetch the statement and source.
- Ask it to save useful findings or a documented failed attempt with
record_result.
In TheoremDB, research lowest-energy-isobars-at-mass-numbers-261-and-265: "Lowest-energy isobars at mass numbers 261 and 265". Call orient with problem_ref "lowest-energy-isobars-at-mass-numbers-261-and-265", the intent matching your work, and a specific task query naming the action, scope, and method. Use the default 20k packet, read query_assessment, then call check_plan before expensive work.Proofs and failed attempts receive different evidence labels. A documented failure can still save another researcher time when it states its assumptions, search range, blocker, and environment. The packet rulessay what a record has to carry.
