Atomic Physics operators

11 operators in the atomic_physics category of the live registry. Compose them in a contract or call POST /api/zeq/compute — KO42 is always on, plus up to three more per call.

How it computes: dedicated closed-form solver solveQM — real equations over CODATA-2018 constants; where an operator needs a series/matrix/field a scalar cannot express, it refuses honestly. See the solvers.

OperatorDescriptionEquation
XION_1Ionization rate operator: electron density times ionization cross-section for atomic transitions.X_{ion}^{(1)} = n_e \cdot \sigma_{ion}
XION_10Tenth ionization operator for charge exchange cross-section modeling.X_{ion}^{(10)} = n_e \cdot \sigma_{ion}
XION_11Eleventh ionization operator for inner-shell ionization threshold analysis.X_{ion}^{(11)} = n_e \cdot \sigma_{ion}
XION_2Second ionization operator for doubly-ionized species cross-section computation.X_{ion}^{(2)} = n_e \cdot \sigma_{ion}
XION_3Third ionization operator for multiply-charged ion production rates.X_{ion}^{(3)} = n_e \cdot \sigma_{ion}
XION_4Fourth ionization operator for high-Z element ionization equilibrium.X_{ion}^{(4)} = n_e \cdot \sigma_{ion}
XION_5Fifth ionization operator for plasma charge state distribution modeling.X_{ion}^{(5)} = n_e \cdot \sigma_{ion}
XION_6Sixth ionization operator for collisional ionization rate coefficients.X_{ion}^{(6)} = n_e \cdot \sigma_{ion}
XION_7Seventh ionization operator for photoionization cross-section computation.X_{ion}^{(7)} = n_e \cdot \sigma_{ion}
XION_8Eighth ionization operator for autoionization resonance analysis.X_{ion}^{(8)} = n_e \cdot \sigma_{ion}
XION_9Ninth ionization operator for dielectronic recombination rate computation.X_{ion}^{(9)} = n_e \cdot \sigma_{ion}

Compute one — a real call​

Ask the operator which inputs it needs (the honesty contract refuses empty inputs rather than inventing them):

curl -sS -X POST https://zeqsdk.com/api/zeq/operator-spec \
  -H "Content-Type: application/json" \
  -d '{"operator":"XION_1"}'
