Endor mims echo.m

Stimulated echo diagnostics for the Mims ENDOR sequence.

Syntax

    stim_echo=endor_mims_echo(spin_system,parameters,H,R,K)

Arguments

    parameters.spins  - working spins, normally {'E'}; spe-
                        cify multiplicity if electron spin
                        is not 1/2, for example {'7E'} for
                        gadolinium

    parameters.electrons - a vector of integers specifying 
                           which spins in sys.isotopes are
                           electrons

    parameters.tau       - the delay between the first two
                           90-degree pulses of the Mims
                           ENDOR sequence, seconds; 200e-9
                           is typical

    parameters.n_dur     - duration of the nuclear pulse,
                           which is NOT ACTUALLY APPLIED
                           within this pulse sequence,
                           seconds; 50e-6 is typical

    parameters.nsteps    - number of time steps to make
                           in the detection period, which
                           runs from 0 to 2*paramters.tau

    H    - Hamiltonian matrix, received from the context
           function, normally powder() in this case

    R    - relaxation superoperator, received from the context
           function, normally powder() in this case

    K    - kinetics superoperator, received from the context
           function, normally powder() in this case

Outputs

    stim_echo - stimulated echo seen in the Mims ENDOR sequ-
                ence in the absence of the nuclear RF pulse
