–––––OP,SIXJ (SIX-j SYMBOL) (5.25):Creates a table of Wigner 6-j symbols used by the sum rules code SIGMA ( Chapter 6 ). OP,SIXJ iscase-independent, thus it can be executed without defining the level and matrix elements scheme. Itcan also be inserted anywhere in the input sequence.–––––OP,STAR (START) (5.26):Execution option to calculate only the Coulomb excitation amplitudes and cross sections, not the γ-rayyields. This comprises a subset and consequently an alternative to OP,POIN. This option can be usedwith either OP,COUL or OP,GOSI.–––––OP,THEO (COLLECTIVE MODEL ME) (5.27):Generates matrix elements according to the geometrical model following the Bohr-Mottleson prescription.–––––OP,TITL (TITLE) (5.28):Reads in the user-given title to be reprinted as a header of the output (maximum 80 alphanumericcharacters). Can be repeated if more than one line is needed.–––––OP,TROU (TROUBLE) (5.29):Performs an analysis at the local minimum to pinpoint erroneous experimental data. This option mustbe inserted immediately before OP,EXIT.–––––OP,YIEL (YIELDS) (5.30):Used for input of data required if it is necessary to calculate the γ-ray deexcitation of the Coulombexcited nucleus. OP,YIEL is mandatory if OP,GOSI has been selected, in which case it is also used tospecify additional spectroscopic information, i.e. branching ratios, mixing ratios, lifetimes and knownE2 matrix elements, as well as relative γ detector efficiencies and upper limits of the unobservedtransitions. The experimental deexcitation yields are supposed to reside on a separate permanent fileattached to the job.INPUT OF EXPERIMENTAL γ-RAY YIELDS (5.31)Section 5.30 describes the structure of the file containing the experimental γ-ray yields from Coulombexcitation.61
